I posted this on another thread, but here's my 2 cents.......
If you are going to eat alot of Counter Service, consider joining Connections to get the meal vouchers for $11, each covers a combo meal, drink, and dessert, and can be good deals. I'm sure you've read about them here on the DIS, but if not, do a forum search or go to Mousesavers.com Don't buy them on ebay, they're really overpriced there.
The vouchers are a really good deal at Tangerine Cafe and Beaches and Cream. I would reccommend eating at Tangerine Cafe (take out in Morrocco in EPCOT) even without vouchers because the sampler platter is big enough for 2, and they have an inside, air conditioned dining area and it is not burgers and fries, so it feels like a "real meal".
Beaches and Cream is also a neat place, and with 3 of you, you may want to try the Kitchen Sink. It is $21, and you're not likely to finish it, so I wouldn't do it without a voucher. Food is okay there, not great, but the desserts are amazing!
Another good deal for budgeters is the Meal Deal at AK (Disney sells this for $10.50 and you get a combo meal, drink and coupon for a bottle of water and either a popcorn or icecream later in the day.) Best place to use it in AK is at Tusker House Resteraunt. We bought 1 deal for the two of us, and used it for a half rotissere chicken, vegetables, and mashed potatos with gravy and a drink, and then bought an extra drink for lunch- about $13 or so total. Then later in the day, we used the snack coupons for a soda and box of popcorn. This is yummy food, and you don't have to buy anything ahead of time.
hope you have a wonderful trip!
