One of the bars in Swan/dolphin has karaoke. That was a fun time. It is staggering distance from Jellyrolls. I'd suggest drinking your way out of Epcot back gate, boat it over and have several red cup specials from Jellyrolls, follow it up with some karaoke. Aren't staying in Epcot resort area? No problem. The lobby couches of Dolphin are quite comfy.
