Disney world was fun,
Disney land blew (of course I was 6 when I went, therefore I chouldnt ride the rides. mickey mouse, you tall bastard! Whats he doing holding a ruler anyway!?).
Tunica mississippi Sucked (gambling) it had nothing for kids (or teenagers).
The grand canyon is always interesting, although if you want a big hole in the ground, it's always less expensive to buy a shovel and get to digging to candy land.
If you live around Arkansas or Missouri, Silver dollar city is a nice change of pace, though they just built this new one next too it called celebration city, and it has a nice sized arcade (DDR anyone?).
California is nice, I lived in Sacramento for about 5 years, I wouldnt recommend Sacramento, or L.A. But any place other than that is nice, watch out of the mudslides

.
Washington (state) is a nice place, I got a chance to go there to see my step brother once, and besides it being cold there alot of the time, it's a nice place (very bright with the leaves in fall).
Las vegas is equaly as impressive as people say it is, although I whouldnt want to live there (other than to be with my girlfriend of course

) It's a great place to vacation.
Arkansas is pretty nice, this year all the leaves turned relitivly quickly so there was really no color in them, but usualy if you drive threw around october you get a nice drive (it'll be romantic with girls

).
I don't recommend Novia Scotica, Canada (For the simple fact that my brother in law lives there... ~_~;;). It's an ok place, they just had a hurrican not too long ago though, pretty weird for that place to get them that far north.
I was born in Flordia, and I still like it, Disney world and orlando are nice, sea world is a bitch, they have some REALLY nice houses on the ocean (and new, they have to replace them after every hurricane, insurence is such a bitch).
Dallas, Texas is nice, if you want to see a tornado.
Oklahoma, same as above.
Anyway, that's about all I can think of, that I've been to myself (sorry for being so long winded
