Hey, you sound just like us! We've got a tribe of five too, and are heading to WDW for a six-day stay in June. We're staying offsite at our timeshare and will be making good use of the kitchen.
Our plan right now is to do two character breakfast buffets. We'll be doing a midday break each day, going back to the TS to cook lunch, have a swim, nap, etc. Then, we'll head back to the parks in the evenings. I'm planning on us doing easy, inexpensive breakfasts - yogurt, bagels, cereal, fruit. We'll also be taking snacks with us into the parks to ward of the hungries.
Lunches will also be easy, comfort-foods - mac & cheese, chili dogs, fruit, veggie trays, chips, etc. I'm not sure about evening meals yet; two of our five are teenage boys who eat like the food is going to run out tomorrow

. I have a feeling if we do CS meals at the park, I'm going to end up buying two meals per boy.
I'd like to do some offsite dining, as well - there are a number of chains in the area that we don't have here at home, but that I used to eat at when I lived elsewhere. Some of these are fairly economical, such as Sweet Tomatoes (soup/salad buffet). I'm planning on hitting up the coupon and restaurant sites to see if we can get coupons, which should save us a little more.
Overall, food is going to account for a fairly substantial portion of our trip cost. We're pre-buying items such as souvenirs, glow sticks/necklaces/wands, and surprising the kids with them, so those will be paid for. We're also signed up for GAD, which we'll be using for tickets as opposed to FPs. All of this should free up extra funds for us to use on special things, such as the character and offsite dining. I'm even flirting with the idea of taking DH to Medieval Times for dinner one night. Should be fun!
Anyway, hope you and your tribe have a great time.
My husband and I and our 5 children are going to WDW next month for 5 days. This is our first trip to WDW. I am very frugal and am trying to enjoy this trip without totally blowing a wad! We are staying off-site at a place with a kitchen, so some of our meals will be eaten at the hotel, but I want to be able to eat at least one meal and snacks in the parks each day. Does anyone have any tips on how to feed a family of 7 (Children's ages range from 1 to 10) in the parks for cheap?
For example, I love the tip to order a double cheeseburger and an extra bun to feed 2!
Restaurant names, portion sizes, etc would be helpful! Thanks so much for your tips!
