Oh yeah, almost forgot: if you're into clubbing, try Pleasure Island and other Disney nightspots. Also have nightclubs and restaurants at Universal Citywalk. Plus great (and pricey) shopping at Downtown Disney. If you're religious, go for Sunday Gospel Brunch (I've been, and I hear it's quite famous) at the House of Blues at Disney.
(I hope this is "outside" of the WDW/Universal realm. You didn't mention SeaWorld either )
