I have a few weeks off of work this summer, and was thinking about traveling with just me and my older DS who is 6.

I'm having a hard time narrowing down the possibilities - Disneyland, NYC, Hilton Head, Colorado?? We live in Texas so want to get to somewhere with not such unbearable heat.

He's really into birds and nature but I think would like a city too. He's pretty enthusiastic about most things. Any suggestions?
