Disneyworld, not Disneyland.
Where to start…
Disneyworld can be awesome for adults, but it’s kind-of a big commitment. If you only have a few hours here and a few hours there, Disney theme parks would be out. It takes days to get the full Disney parks experience, not hours. Downtown Disney (which includes three separate areas) is good at night if you’re into shopping. Plenty of good restaurants are to be found in Downtown Disney as well. Cirque du Soleil has a theater at Downtown Disney.
Basically everything I said about Disneyworld in the above paragraph can be said for Universal Orlando. Universal CityWalk is similar to Downtown Disney, although the last time I looked CityWalk had dance clubs (Pleasure Island’s dance clubs have been closed, IIRC). Substitute Blue Man Group for Cirque du Soleil.
If you really want help planning Disney/Universal stuff I can help you; PM me. I’m something of an expert on Disney trip planning (really, I’m not kidding).
If Disney & Universal are out, there’s the unspeakable kitschy (and unspeakably awesome) Gatorland, an alligator zoo.
PM me and I’ll try to help you some more.
