IMHO this is a bit too high. For quick service maybe $20 per person per meal. Toss in TS for 1 meal $50 per person depending per on what's ordered.
Let's pretend my family is staying at CBR and we'll talk about eating patterns. I've noticed that DH and the kids eat a lot more during these trips - like they do in the summer when they're constantly burning calories. We all exercise pretty regularly, but in the summer DH rides his bike to and from work and the kids are at swim camp 8a - 3p and then swim team practice 6 - 7p. They all can't eat enough and get baby 6 packs, etc.
Anyway, if you are walking a lot, you might eat a lot.
Breakfast at CBR for an adult - muffin, eggs or yogurt, fruit, coffee, juice - about $21 x 2 = $42
Breakfast at CBR for kid - muffin, yogurt, fruit, milk, juice - also about $21
Breakfast total for 2 adults and 1 child = $63, and oh, I think the 6.5% sales tax applies too
Maybe the real total = $67
Snack #1 - churros - $6.25 each x3 = $18.75 + tax
$20
Lunch at MK for an adult at Pinocchio Village Haus - pizza, side salad, coke - about $20 x 2 = $40
And the kids say no I want the adult meal, I'm sick of Danimals and stupid carrots sticks
$60 + tax
Total $64
Snack #2 - slushies and pretzels for 3 - $39 + tax
Total $42
Dinner at Pecos Bills for an adult - Fajita platter and a coke - $19 x 2 = $38
The kids finally wants a kids meal - cheeseburger - $7.50
Total with tax = $48.50
Dessert - 3 Dole whips - $15 + tax
Total = $16
GRAND TOTAL = $257.50
Let's pretend your child is dainty and a picky eater:
CBR breakfast for 3 = it's still about $56
Snack #1, you only get 2 churros and share - $13.50
Lunch, the kids agrees to a kids meal - $50.50
Snack #2 - 3 slushies, but only 2 pretzels - $33
Dinner, same as above - $48.50
Dessert - I'm not sharing ice cream with a kid - $16
NEW GRAND TOTAL = $217.50
Okay, you're not pigs. You only get one snack a day.
SECOND NEW GRAND TOTAL = $204 or maybe $184.50
