We have the
DDP so we will get plenty of sweets with desserts coming with meals. What is your favorite snack that is not a sweet?
For CS meals, if you are getting tired of the sweet desserts, know that you can substitute a bottled water for a dessert.
We also love the eggrolls~ in AK there is also an eggroll kiosk on the path just down from Yak and Yeti. In MK, in Adventureland, there is an eggroll cart between the Magic Carpet ride and the Swiss Family Robinson Treehouse.
Soft pretzels/cheese dip as mentioned, and in MK at Liberty Square Market there are baked potatoes with butter/sourcream/cheese.
You can get a small popcorn (not with a souvenir bucket) and at some of the fresh produce carts, veggies, pickles.
At CS, french fries, onion rings, sometimes a side of mac and cheese. At some CS and kiosks bags of chips.
In resorts, you can get the small bags of Chip and Dale pretzels, nuts, trail mixes, Mickey Head cheddar crackers (like Goldfish), small boxes/packages of crackers such as Wheat Thins, Cheese Nips.
I know there's more too, just what I can remember...
