The Phoenix Tango Marathon is a gender balanced event being held on the Arizona State University campus during the July 4th weekend. Yes it is hot in Phoenix in July but also cheap and after-all the dancing is in-side and the air-conditioning is great.  The Mission Palms Hotel is at the north end of the Tempe district jamb packed with restaurants, bars, boutique shops and just south of Tempe Town Lake where the City of Tempe holds their phenomenal 4th celebration.  The roof of the Mission Palms is the best view in town for the fireworks display on the lake.
