Starting Rolls-DHS; this is good for breakfast or lunch; big sandwiches-enough that you can share if needed
Anything EPCOT has to offer in WS-so many little stands like Morroco has a noodle stand, eggrolls in China, Japan has great sushi and noodle restaurants-but at the TS restaurants, you can always order appetizers and have a great meal in itself and everyone can share.
But, we always take extra snack with us (granola bars, pretzel packs, trail mix, powder drink mixes to put in a water bottle, and chips that we can snack on through the day.) Makes it easier on the wallet bringing things from home sometimes-having a good breakfast and snacking on granola bars (with a fruit bowl at the parks) usually holds us over 'til dinner time so we can splurge a little more.
Definitely consider cutting to 2 good meals a day with snacking in between-that cut my spending a lot. Space your timing out as well-eat a little later for breakfast and a little earlier for dinner-like right when they get ready to change from lunch menu-then you pay lunch prices for the same size. It really does save money.
Have so much fun!
