Cool! I'm glad I was able to help you with the remaining credits with my Earl of Sandwich suggestion! It's definitely a worthwhile thing to get for the road instead of letting the credits go to waste! And who doesn't love another opportunity to have EoS?!? Curious to know which one you like and what you'll end up getting!
When Howard and I were debating
DDP stuff, I tried to figure out how we would use our snack credits. One other thing besides what you listed that I would definitely want to try is an apple turnover from Main Street Bakery (or any of the other goodies!). I'm hoping to get this in February anyway! I'd also want to try an egg roll from the Adventureland cart. I really don't know why I want to, haha. I just feel like some people have talked about having to get one that I'd want to try it! Paying $2 for it doesn't make sense to me, so using a snack credit would've made sense!
I do know that you can get fries or soup from some places too. I'd get those as well. Oh, and if it were warmer out, I'd try a Kaki Gori thing from Japan!
Did you know there's a list of the snack credit stuff on the dining section of DIS? It's right here:
