I'd pick Disney Quest. Its like an indoor, hi-techie park [it has "lands"]. There's a pretty big arcade, a lot of virtual reality, the make your own roller coaster, and my personal favorite, the Animation Academy. You have your own little touch pad screen and there is an instructor who tells you how to draw a different character [character depending on the time you go]. I did Goofy. And if you buy the drawing, you get a pin!
Its a lot of fun. I love the water parks, but I would probably choose DQ if I had the option.
Have fun! Whichever you pick, you will!
