Columbia Harbor House in MK (across from Hunted Mansion) is a great CS meal. We found 2 adults meals of chicken and fish were enough for the 4 of us (saving a CS meal for later.) If it is busy, there is an upstairs to sit in too.
Tusker house in AK is good too.
You can't go wrong with Pizza Planet at MGM (your DS will love the whole Toy story theme.)
The land at Epcot has a good CS place. Very good for the Dinning plan because it is pretty pricey for CS.
If you like seafood Coral Reef at the Living Seas is only one TS and is good (but $ food). It can be a great meal with the Dinning plan. Make sure to get ADR's in advance.
Speaking of Epcot, don't skimp on it because you assume you DS won't like it. There is so much to do there and stuff for kids too. There are Kid ______ masks to decorate for each country. There are also tag necklaces to decorate at many of the FW locations (The land, Living Seas, Test Track, Inventions, and maybe Mission space.)
Also there is a fun play area in the back of mission space while you wait for someone to ride it. In addition they have one part that is "green" meaning it doesn't spin and you aren't going to get sick that if you DS is tall enough he might enjoy. My DD was not (I think it is 44 inches). The wait wasn't as long for the green one.
Also there is a ton of fun things to do in Innovations. Spend some time there. If you have a Disney Visa you can get a free picture (from 1:30 to 4:30.) Oh and the light up sidewalks near there are night are a big hit.
BTW, Hi. I am Mrs. PhD too if you haven't figured it out. Glad you came over here. :wave:
