Well, good suggestions already (and I didn't know there was an Orlando forum). It turns out that I got an amazing hotel deal (five nights for a hundred bucks) and flight (next to nothing), so I'm blasting out of New Jersey for a bit of sun. In fact, I'm at the airport right now. :-)
No real budget to speak of, but I don't spend foolishly (no yacht charters for me!). I've pretty eclectic interests, but golf is not one of them (so that rules out a LOT of activity, it seems!). I like the water so a park might be in order.
Thanks for the suggestions and feel free to suggest more!
