We are on the meal plan. So what i should have said is that we are not doing any places where dinner counts as 2 "sit down dinner meals".
The place on the top of the contemporary is one such example. Also, Canada(steak house) at Epcot is another example.
Why save? If I want a good meal it won't be at Disney. Simple fact is that food prices there are higher than reasonable. I can walk down the street from my house (1/4 mile) and eat at one of the best restaurants in the state of CT. I've eaten there once because as good as a $20 hamburger is, it is still a $20 hamburger. Point is, if I spend an extra $20 at Disney it will be on something that I can't buy/do elsewhere.
This was our same reasoning when we went this past Xmas. Having kids about the same age, we booked the restaurants based on the characters mainly for the kids and convenience. They get to relax and the characters comes to the table to take pictures and give autographs vs us waiting in yet another line. It's all about the Disney atmosphere, definitely not there for the food. We went to a couple of the ones were on your list:
Magic Kingdom:
Crystal Palace
Pooh/Tigger and pals - food was the best of all the restaurants we booked
Epcot:
Akershus Royal Banquet Hall
Various princess characters (Ariel was hot)
Grand Floridian Resort (hotel on monorail):
Cinderella - the stepmother played her part really well - buffet was ok
By the way if you get the meal plan, we didn't know this until half way thru our stay but you can buy the adult meal using the non-reserved meal ticket credit. There's no distinction whether you use the same credit to buy adult meal or kid's meal (except you get half the amount of food buying kid's meal). One adult meal would feed more than two kids, they do give you a lot.
Have fun. It was my first time there and I was pleasantly surprised expecting it was just for kids. It was nice to shut out the real world for a couple days.
