We Took 15 People to Mexico. I Survived on Spreadsheets and Prayer.
In June 2023, fifteen of us landed at Cancún International. Cousins, in-laws, a couple of close friends, my wife, and our three kids — twins who were five at the time and our youngest at two. The destination was Finest Playa Mujeres. A week of all-inclusive bliss. At least that was the pitch when I sold everyone on it six months earlier.
I'll tell you how that trip went. I'll tell you what it actually cost. And I'll tell you why, about six months after we got home, I started building the app I wish I'd had from day one.
The Setup
Finest Playa Mujeres sits on a stretch of Caribbean coast about 45 minutes north of Cancún proper. Quieter than the hotel zone, fewer 21-year-olds doing tequila shots at 10 a.m., more families and couples. It's the kind of resort where your kids can disappear into the pool area for two hours and you're genuinely fine with it.
For our family of five, we booked a Club Level Family Suite — and this was the single best decision I made during the entire planning process. The kids had their own separate room with bunk beds. My wife and I had ours. We could close a door at bedtime and have an actual conversation without whispering. For eight nights, the suite ran us right around $8,000.
That's not cheap. But I'll tell you what. When you have a two-year-old who falls asleep at 7:30, and you're trying to survive a family vacation with any shred of sanity, paying for a separate room for the kids is the closest thing to luxury that actually matters.
The rest of the group spread across the resort in a mix of Junior Suites and Swim-Up rooms. Some couples splurged, some kept it lean. Total group cost for the week? Somewhere in the neighborhood of $55,000 once you add everyone's rooms, flights, transfers, and the random tabs that pile up on a group trip. More on that pile in a minute.
The Moment I Knew I Was in Over My Head
It was a Tuesday night. Four months before the trip. My phone was buzzing nonstop.
I had a spreadsheet open on my laptop. I had a Notes app open on my phone. I had a WhatsApp group with fifteen people in it. I had three separate Venmo threads. And someone — I won't say who, but it was an in-law — had just sent me $450 with a note that said "for the thing."
What thing?
I sat there for a full minute trying to figure out what $450 corresponded to. Was it the resort deposit? The excursion deposit? Their share of the private airport transfer? Someone else's share that they were paying on behalf of?
Eventually I messaged back: "Amazing, thank you!" Because at that point I was too proud to admit I had no idea what they were paying for, and I figured I'd match it to something later.
I never did match it to anything. To this day, I don't know what that $450 was for. If you're reading this and it was you, we're square. Probably.
The Things That Went Wrong
Let me give you the highlight reel of the planning chaos.
The deposit roulette. The resort wanted a 25% deposit per room about five months out. I was the one with the contact at the travel agency, so naturally I became the bank. I paid the total deposit up front, then spent the next three weeks chasing individual amounts from fourteen other people. Some paid within a day. Some "forgot." One person paid me in cash at a birthday party, which I then promptly lost in a pair of pants.
The spreadsheet of doom. I had a Google Sheet with tabs for Rooms, Flights, Excursions, Transport, Meals Outside Resort, and "Misc." By week four, the Misc tab had more rows than the others combined. What was on Misc? Things like "Gabby's sunscreen run - $22," "Tip for guy who brought us extra towels - $15," "Gas money for airport run - $40." It was unmaintainable and I stopped updating it around day three of the trip.
The group chat that ate my soul. Fifteen people in one WhatsApp thread. Multiply that by the 180 days of planning. At one point someone asked a question about flight times, and by the time I'd scrolled through to find the answer, three other people had asked the same question and one person had started planning a completely different excursion.
The "who's paying for what" gray zone. When you have cousins and in-laws on a trip, there's a social weirdness about money. People want to be generous. People don't want to seem cheap. People also don't want to be the ones stuck holding the tab for a dinner that spiraled into a $600 margarita situation. I tried to handle this through sheer goodwill and mental accounting, which worked about as well as you'd expect.
The One Thing I Absolutely Nailed
Before we left, I booked a private transport from our house to the airport for nine of us flying out together. Two SUVs, door-to-door, no parking, no shuttle buses, no "meet me at terminal B" confusion. Cost us about $280 total, split across three families.
It remains, to this day, the single best trip planning decision I've ever made. We rolled out of the driveway at 5:30 a.m. with bags, kids, car seats, and coffee, and we didn't think about logistics again until we landed in Cancún. If you're traveling with a group and you're on the fence about private transport versus everyone figuring out parking, just book the transport. It pays for itself in sanity.
What the Trip Actually Cost (The Real Numbers)
Let me pull this together. Rough per-couple numbers for a week at Finest Playa Mujeres in June 2023:
- Resort (Junior Suite, all-inclusive): $4,500 to $5,500 per couple for 7 nights
- Flights (East Coast → Cancún, round-trip): $450 to $700 per person, depending on how early you booked
- Private airport transfer (each way): $60 to $100 per person, depending on group size
- Excursions during the week: $150 to $300 per person (we did one boat day and one off-resort dinner)
- Tips, extras, random souvenirs: $200 to $400 per couple. You think it'll be less. It's never less.
Rough total per couple: $5,500 to $7,000 for a week.
Our family of five in the Club Level suite: around $9,500 all-in, including flights, transfers, tips, and one very expensive stuffed flamingo that my youngest refused to leave Mexico without.
What I Kept Thinking, The Whole Time
Here's the thing. Every time I ran into one of the planning problems above, I'd think: there has to be a tool for this.
I'd look. There wasn't.
There were itinerary apps that could tell me my flight info. There were splitting apps that could settle up the dinner bill after the fact. There were general budgeting apps that could tell me how much money I had left in the checking account.
Nothing for the thing I actually needed. Which was:
- A single place where everyone in the group could see the shared budget
- A way to track who had paid what, without me being a human ledger
- A clean breakdown of where the money was going, updated in real time
- The ability to settle up at the end without me chasing people with Venmo links for three months
So about a year and a half after we got home from Mexico, I started building it.
Introducing the Tool I Wish I'd Had
PlanFare is a trip budgeting app I built specifically for people who plan real trips in the real world. Weekend getaways, big family vacations, work trips, cruises, road trips. The kind of trips where there are a few people involved and the logistics get complicated fast.
Here's what would have saved my sanity in Mexico:
Travel Circles. Save your group once, plan trips with them over and over. The fifteen people who went to Mexico? Most of them would go on another trip together in a heartbeat. In PlanFare, they'd be one saved group. Next trip is two taps to add everyone, not fifteen.
Shared trip budgets. Everyone sees the same budget. Everyone sees what's been paid, what's outstanding, what category the money is going to. No more "wait, did you pay the deposit yet?" texts in the group chat at 11 p.m.
Automatic settle-up. At the end of the trip, PlanFare calculates exactly who owes whom with the minimum number of transactions. Not "you owe Gabby $47.50 and Gabby owes Mike $62 and Mike owes you back $15." Just: "Send Gabby $47. You're done."
Categorized tracking. You can see at a glance that you've spent $2,400 on activities but only $800 on meals outside the resort. That's useful information for next time. Or for telling your spouse why the credit card bill is what it is.
Quick expense entry. Snap a photo of a receipt. It extracts the amount, category, and date. Log it in ten seconds while you're standing in the resort lobby holding a cocktail and a two-year-old.
The Honest Pitch
I built PlanFare because I lived through the Mexico trip and realized the tool I wanted didn't exist. The free tier lets you plan one trip at a time with full features. No credit card needed. If you find yourself needing multiple active trips, it's $4.99/month or $34.99/year. That's it.
If you're in the middle of planning a group vacation and this post has you nodding along, sign up free. You don't have to take the Mexico trip I took to deserve a better planning tool.
And if you're that in-law who Venmo'd me $450 in 2023 for "the thing" — I still don't know what it was for. But thank you. Genuinely.
