uhm, Disney World, I don't think so. Not at all. The grand canyon DEFINITELY... one of the best places--but you have to go down one of the trails INTO it, not stay on the rim with all the tourists... I know. I've done it. One of the best trips I ever had. It's definitely better out in nature & away from civilization & cops... paranoia will give you a very bad trip... which is why I doubt Niagara would be very good... It's too crowded & built up... Antartica would be perfect, if it had convenience stores!
