Hi Stacey!
It's always a pleasure to answer questions for a fellow resident of the Garden State. I'm glad you stopped by the Disney Parks Moms Panel.
You're going to love
Cape May Cafe, located just off the lobby of
Disney's Beach Club Resort. I have always been a fan of their dinner buffet. My teenage son could eat their Snow Crab legs for hours.
If Epcot is closed by the time you conclude your dinner at Cape May Cafe, you will not be able to gain re-entry to the park. However, that shouldn't be a problem at all. Just board the boat at the back of Disney's Beach Club Resort headed to Disney's Hollywood Studios instead. (You don't have to enter Disney's Hollywood Studios to access their resort buses.)
So, enjoy your meal at a leisurely pace and know that
complimentary Disney transportation will be available to return you to your home resort when your meal is over.
Wishing you many magical memories on your upcoming trip,
Jill
