[LottiesLot]

My girls were 6, 8 and 10 when we were last there. We have enjoyed all the meals on your list (except Artist's Point, haven't been there) . A must do for us is breakfast at Crystal Palace on the first morning. We also enjoyed the Snow White Storybook dining dinner at Wilderness Lodge and Coral Reef was a delicious, cool and relaxing lunch on a hot day in Epcot.
Actually thinking about it we didn't enjoy T Rex, it was crowded, we didn't get a great table and the food was only so-so.
