For a really nice southwest vacation consider Cochise County in Arizona. The unique history, architecture, landscape and things to do will leave you with many memories.
The Hotel Gadsden in Douglas, Arizona is full of history. Some say that Pancho Villa even rode his horse up the stairs inside.
Lots to see in Tombstone, Arizona. The courthouse museum is one of my favorites and is filled with memorabilia and artifacts from Wyatt Earp’s days there as Marshall.
Bisbee, Arizona is a quaint little town that has shops, mine to visit and lots to see. It’s fun to walk around downtown. The Queen Mine tour is really something. 
St David, Arizona has a monastery that is very peaceful to visit. Great for birding too.
Driving through Sierra Vista, Willcox, and Benson, Arizona the scenery changes each time. Higher in elevation, it is cooler in the summer. The Dragoon Mountains are also beautiful. Benson was on the historic Butterfield Overland Stage Route. Willcox is becoming famous for its wine vineyards. Sierra Vista is home to the Historic Fort Huachuca.
