Phoenix is a metropolitan area spanning across hundreds of square miles, home to about 5 million people, so it would help if you could be more specific about where you'll be staying, any particular special interests, etc. I'm sure many of us here would be happy to steer you toward the highlights. If you're headed from Phoenix to Bisbee, I highly recommend paying a visit, enroute, to Karchner Caverns State Park for one or another of the literally awesome cave tours, and also stopping in at Tombstone, where the Allen Street tourist kitsch is entertaining, and the nearby Territorial Courthouse, now a State Park, is authentic and historically interesting, and where the Longhorn is the best place to eat. In Bisbee, visit the Copper Queen Hotel, which has a decent restaurant, the Mining Museum, just a few steps down from the Copper Queen, and if time permits, take the underground tour of the Copper Queen mine itself. In any event, take time to peer into the open pit mine just south of downtown, for a minor example of how men and machines can alter the Earth. Near Bisbee, at Douglas, the Gadsden Hotel is an marvelous example of architectural extravagance, and also home to a surprisingly good restaurant. Have fun, enjoy your visit, but please go back home --- Arizona remains closed to any further legal immigration...
