once you get on the east coast there are lots of parks really close. check Jet blue once you get your start destination. if you book far enough ahead they are really cheap. you can just do a group of one ways and then end up back where you started so that your trip there and back are not too bad. 2 parks in NY, Boston, Baltimore, Cinci, Philly, Pittsburgh... none more than a short flight. besides, you dont want to sit the family in a car every day. lol you get enough of that where you live just getting anywhere.
I've been to some parks, but none of the new ones. I'd like to go back to Pittsburgh again. I was at Three Rivers in 89 before that got Demoed. New park looks amazing.
