L.W.
We loved using our plan. We could have anything on the menu, drink and dessert and it was more than we could eat. We didn't need every meal so we used two credits and went to the Brown Derby the last day for dinner and relaxed. Make reservations before you go for dinners using their online system...character restaurants are often two credits, but we lucked out and went to one that had Winnie the Poo characters that was only a one meal pass. Our two year old pitched a fit when we didn't get in line to get Piglet's autograph and the place was a God send. The food and atmosphere of the eateries was great and we couldn't afford to take advantage of them without the plan.
We went to a Seafood place in Epcot that had a tank with scuba divers and swimming by. Liked the French Bakery there too, and should have used more lunch tickets there. MGM: make reservations for the old-fashioned cafe I think it was the 50's cafe, and clean your plate and mind your manners...great fun!
Two more tips: You can use a snack credit sometimes to get cereal and milk or, we just didn't want to mess with taking the time for this so we brought fruit and granola bars to put off hunger. Ate an early lunch or had a snack and then late lunch (we were able to look for seatings that were less popular this way) and if we had an early lunch we tried to do an early dinner. That way we got to go to popular restaurants by being flexible with times. Have fun!
