The lake cabin beat the theme park, and I kept the receipts

The question

Do you fly the family to the big theme park for a week, or drive three hours to a lake cabin and call that a vacation?

Last spring I had a spreadsheet that said theme park. My wife had a hunch that said lake. One of us was doing math. The other one was right.

The Dad Math

I did this version in the driveway, on the back of a hardware store receipt. Family of four, six nights. Every number in this column is an example. Swap in your own.

• Flights: 4 tickets at $350 = $1,400
• Hotel: 6 nights at $250 = $1,500
• Park tickets: 3 days, 4 people, $150 each = $1,800
• Food: $150 a day for 7 days = $1,050
• Total: $5,750
• Divided by 7 days of pure joy = $821 a day
• Divided by 4 people = about $205 per person per day

"That's less than a nice dinner and a ballgame," I announced to nobody. I was holding a tape measure. I don't know why.

Driveway verdict: book it. I'll download the app that tracks ride wait times. We deserve this.

The problem was everything outside the park gates. The bigger problem was the unit. I priced it per day, and nobody remembers a day. They remember a moment.

The real math

Step one: add what the receipt forgot. Still examples.

• Airport parking, 7 days at $25 = $175
• Checked bags, 2 each way at $35 = $140
• Rental car or rides for the week = $450
• Dog boarding, 7 nights at $50 = $350
• Souvenirs. I budgeted zero. Children budget differently. Call it $250
• Park food costing more than my $150-a-day guess = $200

That's $1,565 extra. New total: $7,315.

Step two: count the time. Use an example value of $30 an hour.

• Planning: my 20 hours of ride strategy plus her 25 hours of packing lists, reservations and locating everyone's other shoe = 45 hours. Her 25 were the useful ones.
• Recovery day at home: laundry, groceries, a tired seven-year-old. Two adults, 8 hours each = 16 hours.

That's 61 hours at $30 = $1,830. Real total: $9,145.

Step three: change the unit. A memory, for this column, is a story a kid tells without being asked a year later. Eleven months after the trip, I asked mine at dinner. In my example household the theme park scored four:

1. The castle fireworks.
2. The roller coaster my son rode twice and I rode once, regrettably.
3. The hotel pool.
4. The time Dad lost the car in the parking garage and found it by pressing the key fob on every level.

Notice that two of those four, the pool and the garage, are available at any hotel within fifty miles of your house.

$9,145 ÷ 4 = $2,286 per memory.

Now the lake. Same family, same six nights, still examples:

• Cabin: 6 nights at $200 = $1,200
• Gas: 360 miles round trip at 25 mpg = 14.4 gallons. At $3.50 a gallon, about $50
• Groceries, cooking at the cabin: $80 a day × 7 = $560
• Canoe rental for the week = $150
• Bait, ice cream, a deck of cards and a mystery tackle box from the general store = $100
• The dog comes along: $0. He considers it the best week of his life.

Money: $2,060. Time: 10 hours of planning plus 8 hours of recovery, so 18 × $30 = $540. Real total: $2,600.

The one-year count was six:

1. The bass my daughter caught. It grows two inches every time she tells it.
2. The thunderstorm night the power went out and we played cards by lantern until Mom won everything.
3. The raccoon that opened the cooler like it had done it before.
4. My son learning to paddle in a straight line, eventually.
5. The pancake that hit the ceiling.
6. Lying on the dock counting stars, which cost nothing at all.

$2,600 ÷ 6 = about $433 per memory.

That's roughly a fifth of the theme park's cost per memory. Check my arithmetic. It holds.

Two notes that aren't jokes. First, every kid in that canoe wore a properly fitted, Coast Guard-approved life jacket, buckled, every single time, and so did the adults. A cheap vacation is only cheap if everyone comes home. Second, we left the cabin cleaner than we found it and restacked the woodpile higher than it was. It takes twenty minutes, and owners remember the family that did it.

The verdict

Cost per memory isn't the only number, and I'll concede it right up front. Some things the lake can't sell you. The first time a kid sees the ocean. Grandparents who live across the country and won't always be there. A trip timed for when a kid is old enough to hold onto it. If that's your reason, the big trip can win, and it should.

But "everybody at school is going" isn't a reason. That's a sales pitch.

So use two rules of thumb.

The trade rule. Divide the big trip's real total by the close trip's real total. In my example, $9,145 ÷ $2,600 ≈ 3.5. That's how many lake weeks you're trading for one park week. Then ask the kids at dinner, "One week at the park, or three and a half summers at the lake?" Watch their faces. They'll do the math faster than you did.

The age rule. Most of us remember very little from before kindergarten. If your kids are that young, go close and cheap. The big trip at that age is for you and the photo album. That's allowed. Just price it honestly.

Run your own numbers in the BRO cost-per-use calculator, and include the time. If you and your wife come up with different totals, that's a conversation, not a contest. When you and your wife don't agree about money covers how to have it without the silent car ride home. And if the canoe lesson sounds small, read what a father in the house is actually doing. The straight paddling line counts.

My wife never opened the spreadsheet. She asked the kids what they remembered from last summer and booked the cabin before I finished explaining wait-time apps.

The bass is fourteen inches now. It was nine.
