I'm not sure if this is what you are talking about, but if you are really budgeting minimize the amount of WDW food you eat.
One particular vacation we just had one day at at WDW theme park (Magic Kingdom), but here is what, for example, we did for that day. It was a trip with an extended family group (10 people). We stayed at an offsite condo (two condos actually) and started the day with a big breakfast (made from groceries we purchased at the Piggly Wiggly) there (early breakfast as we did rope drop -- This is before all the new Genie plus stuff when you could still do this offsite by avoiding days with extra magic hours). We also had a soft sided cooler and cooler backpack and made 15 sandwiches for 10 people that we brought into the park. We also in those coolers brought juice boxes, cracker/cheese/peanut butter snacks, and fresh fruit (blueberries and strawberries). WDW lets you bring your own food in.
It was a busy time at the parks, so we for lunch didn't stop, but whoever was hungry when we were walking from ride to ride grabbed something from the cooler. Grandpa had a
scooter, and we'd leave the soft sided cooler with his scooter when going on attractions. The food kept most in our gang satisfied all day. Three of us, did stop for some table service burgers around dinner time. The other seven held off until after fireworks. Two of us got Mickey Bars during the fireworks. Then after fireworks were done, we went thru Wendy's drive thru, got some things from there on their bargain menu and went back to the condo and the seven that didn't do the dinner at the Table Service place ate Wendy's food with salad and fruit we had bought at the grocery store back at the condo.
We had the whole group helping with food preparation etc. and it was fun. We were actually trying to see how economically we could do food. Your own food is both cheaper and healthier. And so sorry lol -- I am one of the two people who splurged on a Mickey Bar. It's my special treat to myself when I go to the MK and I got one for my son too.
We were really into budgeting on this trip. Our other two theme parks for the week were SeaWorld and at that time they had a second day free deal. And we all love that park. And our other three days were resort days -- lots of pool time, hot tub time, tennis, game room stuff that the condo, some family games, and some family movies that we watched at the condo too. Great hang out time with the cousins, grandma, grandpa etc. I think our kids enjoyed those days as much or maybe even more than the theme park days, but having both was a fun combination (we do love the theme parks), and overall made for a pretty budget friendly Orlando trip.
