what do you like doing? there's usually music at house of blues or other places around springs. Many love jelly rolls at boardwalk. there is all of central florida just outside of property.. maybe the dr phillips art center that disney built has a show or performance you want to see... (not a far taxi/uber and short drive). If your drinkers then abracabar in boardwalk is new and interesting, trader sams in poly is a unique experience. there are some interesting dinner shows not too far off property..
the holiday show at epcot is nice if you've never done it and worth doing more than once if you have. I think it's called candlelight processional or somethign like that... you could probably make an evening out of touring the monorail resorts and wilderness lodge to see their holiday setups (giant gingerbreads, largest tree on property), etc.. hoop de doo review is an interesting dinner theater at ft wilderness experience..
I can't speak much for universal, I've barely been there.. but it's helpful to know what your interested in and what type of traveling your really willing to do because disney or universal.
edit to add: gaylord palms is very close to property and their ICE exhibit will be started by december (they give you a coat, it's a winterland made of ice, don't know this years theme). See if swan or dolphin has anythign interesting on the calendar also, around here they do something like their own mini 1 night food and wine show.
