You can use CS credits here, but for what might depend on the cast member who rings you up.
We were there last week and to use a CS credit we had to have a sandwich, a sweet and a drink. We couldn't get two sweet items. I tried, but was told I had to use snack credits for most of the sweet items since I only had one sandwich.
They have a ham and cheese croissant for breakfast that counts as the sandwich. For lunch or dinner they have hamd and swiss or turkey and brie on honey wheat for sandwiches.
This really is a great place to use CS credits. For breakfast you can get the ham and cheese croissant, a huge pastry, and a smoothie (strawberry or cappucino). Other times you can get the ham and cheese or turkey and brie sandwich, any pastry (including the HUGE cookie ice cream sandwich) and the aforementioned smoothies. Can you tell we like those smoothies
. If you get a cast member who lets you get two sweet items all the better!
