Lots of fun. Museum has fun for young or old. I didn't go up into the arch this trip but it is lots of fun, although rather expensive. I would make sure you go up at least once. Be aware that you have to take off your belt when going through security. I hate having to do that. So if you can wear pants that don't need a belt that is what I would advise.
