My son and I are doing this on our next trip.
We're doing the ice cream social in Epcot. We have PS for Sci-Fi, and Prime Time Cafe. We'll just order some type of dessert and maybe shakes at each one.
There so many great restaurants in the world, this is the only way for us to experience some of them without breaking the bank.
I want to add Brown Derby and a few others to the list.
