There isn't really a CS option at the YC. There is Hurricane Hannah's at the pool for lunch and dinner. The Marketplace at BC has what would be considered close to CS, but the options are extremely limited - no waffles or pancakes with bacon. . When we wanted CS we would go into Epcot or plan to eat at one of the other parks. It is one of the disadvantages of staying at the YC/BC or BWI. I don't know of any soft serve ice cream machines at the YC/BC. Beaches and Cream restaurant sells real ice cream, though. ETA: By real, I mean hand scooped ice cream.
