If you're going to be in Orlando, Florida for Disneyland then don't miss out on getting out to NASA while you are there. Awesome!!

I loved Las Vegas, ended up going back there to get married, but it's not a town for kids so perhaps just get out to the Grand Canyon instead.

And New York is a must! There is heaps to do in NYC, Broadway, shopping, Central Park, Grand Central Station, the big toy place, can't remember what its called...

Have a great time!
