If you're already at Epcot, you can walk over. Usually, you can catch one of the magicians or BW entertainers either on the BW or inside the resort. There are some carnival type games as well. That's usually about it, but the entertainers are definitely fun! This time of year they are there at around 8-10pm-ish, not sure about September. There are also a few restaurants and shops, and the Boardwalk Bakery has great treats! If it's a nice night, you can do the loop around and go by BC and YC, too and back through Epcot since I think it's EMH on Friday nights.
