It depends on what you like to do. Do you like to play golf? Shopping? Fine Dining?
I know this is a Disney thing, but be sure to see the Cirque du Soleil at Downtown Disney one evening. Tickets are about $70 each.
If you like to golf, Disney has some nice golf courses, though expensive. This winter, they had to cut their green fees dramatically, as they planted the grass seed too late -- the grass was brown in December.
