M.,
I am chiming in late, and please ignore Margaret K.'s post it was rude and not very helpful. Also look into Sabino Canyon for hiking. There is also the Pima Air Museum (www.pimaair.org) this is one of the biggest air museums and also has a huge "boneyard" you can take a shuttle over from the museum and walk around and check out all of the retired military planes along with some presidential planes. There is also Old Tucson, but if you are on a budget take the drive to Tombstone and walk around there, it is more like a town where as Old Tucson seems more staged to me. As other posters have said Mt Lemmon is great for hiking and so is the Desert Museum and walking around Fourth Avenue. You might want to walk around the University while there, it is a really nice campus to visit. I also second El Charro for good Mexican Food and Pinnacle Peaks is fun for everyone and is casual(there is a website for this restaurant if you want to check it out, just google it). There is plenty to do in Tucson for a week, I always feel as if I never have enough time to do what I want when there, but I do love to visit. Let me know if you need or want any other information. Have a great family vacation!!
