Hi.. we have done the Meal Deal twice..
I don't remember breakfast.. I think it is only lunch, afterlunch, second lunch , snacks, pre dinner, dinner etc..
My kids and Dh loved it..and it was definetely worth the money..
"The Meal Deal is available daily from 11 a.m. until 30 minutes prior to park closing, and is valid for one entree platter (described below) and one dessert (usually a cookie, mini-Bundt cake or Jell-O parfait, dependent on restaurant) per trip through the food service line."
We had fruit plates and salads and burgers and chinese and pasta and I must be forgetting things..The average meal is $10 per person and if you plan on eating lunch and dinner at the parks it pays for itself.. and the rest is dessert and extra snacks..
We bought the mug
"
Purchase a One Day Meal Deal Sipper Cup for an additional $8.99 plus tax which allow you unlimited soft drink fountain beverages at participating Meal Deal locations only in Islands of Adventure and Universal Studios. The Sipper Cup can only be purchased when a Meal Deal is purchased. " and everyone shared the mug.. it also is refillable for subsequent days too.
