We're planning a short trip over the July 4th weekend - will go to MK on Fri, Epcot on Sat, and MGM on Sun. This needs to be a low budget trip so I'm thinking about only getting a PS for dinner at MGM on the 4th and just doing counter service or going back to the resort (ASMo) for the rest of our meals. Would this be a huge mistake? I know the parks will be really busy but I was hoping that since we're pretty familiar with the counter service options at MK and Epcot and we don't mind eating at off-times that maybe it would work. This is our first time going on a holiday weekend, tho, so I would appreciate any advice I can get. TIA
