In the past couple of years, you got 3 snack credits and they make it pretty clear where you can and cannot use them in addition to unlimited mickey bars, ice cream sandwiches and strawberry bars. With the exception of typhoon Lagoon, there you get unlimited ice cream bars as above but also unlimted popcorn, grape and apple slice bags and soda.
Prior to covid, you got a counter service meal, other years counter service restaurants served unlimited burger, fries, hot dogs, etc.
Personally I prefer the 3 snack credits. EP and AKL they have a good mix of sweet and savory usually enough to make a meal. At HS, it's a lot of sweet stuff beyond popcorn and mickey pretzels.
