It's all perspective. OP is spending more per person for food/incidentals than we spent per person for our entire Disney trip.
$57 pp per day the amount for spending and incidentals?? I sound like a broken record, but I'm just wondering if the people who think this number is that high really add up everything they spend money on for their vacation. I think of myself as being fairly conservative in my spending, but maybe not compared to others on this forum. This number is just right on for us: It covers groceries (more on vacation than at home and healthy food (fresh fruits and veggies can add up, but are good for you and so nice not to have to have all meals out)), a few souvenirs, incidentals at Walgreens if you forgot something or want to print photos, reading materials if you are bored at the airport with delays or want something new to read on a long driving trip, etc., counter service and snack at the parks anytime you are hungry or in the mood for a Mickey Bar, and eating a modest dinner or two out or ordering pizza if you feel like it. // I' d cut back vacations days before I'd cut back on this I think.
Here's our last week long trip and approximate expenses for two for food and incidentals. Like OP we were offsite, but in an offsite condo rather than an offsite house (really similar). Also, we had three others staying with us, so we shared some of our groceries, bought pizza to share one night, etc. They shared with us too.// Unbelievable but we hit $55 per person per day, almost exactly what OP budgeted.
Food and incidentals
Food at airport -- $25
Books and magazines at airport -- $30
Grocery trip 1 -- $120 (All breakfasts, three lunches, and one dinner in) // did one other grocery trip too. We don't really save all that much money eating in, but we eat way healthier and really enjoy not having to go out for every meal. Love/Love/Love my own kitchen on vacation. Things like garbage bags, laundry detergent, paper towels, laundry soap, dryer sheets, aluminum foil, zip lock bags, etc. eat into vacation grocery expenses too. At home, we'd already have these things that cover multiple weeks.
Lunch, Dinner, and snacks/drinks at parks (3 park days) $30 pp per day -- $180
Disney song book -- $30
Refrigerator Magnets -- $15
Dinner at Sweet Tomatoes -- $25
Grocery Trip #2 to pick up a few more things -- $60
SeaWorld souvenirs -- $30
Pizza Delivery (treated extended family too) -- $40
Gas Contribution -- Cousin from Tampa had car we all used -- $40
Parking for three park days -- $14*3 = $42
Develop pictures and other incidentals at Walgreens -- $30
Food and snacks at airport going home -- $25
Airport parking back home -- $80
Grand Total for seven nights/six days food and incidentals = 772
772/seven days / two people = $55 per day per person
Always budget lodging, car, and theme park tickets separately.
OP -- You and I think alike for food and incidental budgeting.
