Hey, if you have time while you are in Tucson, hop on over to Kitt Peak Observatory for a few hours. Its well worth the hour or so drive up there.
How long do you have to decide on the trip? Plane ticket prices should be pretty steady for a few more weeks. The main trouble would be the concert tickets selling out. It may be possible to put off buying the tickets for a bit, try NOPs idea, and then go from there.
