Epcot fav. snacks: anything from the Patisserie in France or Bakerai in Norway (school bread my favorite as well as the cheese soup), DH thinks beer is a snack, the newer Karmel Kuche in Germany has everything caramel
MK fav. snacks: ditto the Dole Whips and floats, egg-rolls from the egg-roll wagon near the Dole Whips, sweet cream-cheese filled pretzels at the Lunching Pad, caramel corn or funnel cakes at Sleepy Hollow
have fun and enjoy. Will you get to enjoy Artist's Pointe, a signature dining option at WL? (Their mushroom soup is amazing.)
