Tell me your thoughts on the Houston Space Center... I'm looking for something to do the day before we cruise out of Galveston. This is looking really good to me. I want something fun & educational for the kids (5 & 2ish). Plus something fun & educational for me and DH that we have never done before. I never been to anything NASA or the likes before. What did you like/dislike? Any other tips? I've read that you can get free tickets to the Kennedy Space Center through your congressman. Can I get them free here too?
