No, neither take ADR's.
Beaches and Cream is a very small space, so it is very crowded at traditional meal times and as Epcot closes. The best bet is to go right as they open in the morning for lunch or other non-traditional meal times.
There will be a line at ESPN to get in. If there is a big game going on it is long and very crowded. It is possible to sit in the bar and eat and we have done that.
Have a Great Trip
