Just booked airfare from Rochester, NY to Phoenix, AZ in February 2010 and am planning a roadtrip to include AZ, NM and Texas. We fly out of Houston 8 days later. We have two children who love adventure and want to see the best places in these three states. Grand Canyon/Sedona, maybe Santa Fe, maybe a dude ranch in Texas? I have no idea..so please send any great places to stop, we will be staying at Mariott properties along the way...Thanks.
