fly the ocean in a silver plane....see the jungle when it's wet with rain....
Really, I think Egypt/Isreal would be up there for me. I guess it depends how old the 4 kids in that family of 6 are. Maybe the Netherlands would be cool too because I could work in a theme park I've always wanted to go to(Efteiling), go to Giethoorn, the bigger cities, have some bike rides through the country. I don't know, never been there.... I think that would be a good place to take a family though...tack on Bruges and Ghent
