Phoenix has no real night life, unfortunately. However, there is a ton of stuff to do and see. A really beautiful place to stay is the Westin Kierland in north Phoenix. Near some really nice restaurants and great shopping. For kids, there is a cool science museum, The Heard Museaum concentrates on Native American history in the AZ area.OF course there are the Diamondbacks baseball team, inclusind the Big Unit. You really have to have a car, the Phoenix Metro area is as big as almost 4 Atlantas. It is made up of several cities, each running into the other. ALl the nice resorts have great pools, you may also look at the Pointe Hilton Resorts, at both South Mountain and Tapatillo Cliffs. ThHey both have really fun pools and good places to eat. There is a place called Pinacle Peak, north of the city, it has an old west town recreation area, and the restaurant is casual and fun dining. If a man wears a tie into there, they will cut it off. AZ is a much more casual state than the east coast. Most places, men don't wear ties or jackets to work, women don't wear pantyhose. (Can you tell I would rather still live there than here?). If you want to see some true local info, go to
www.azcentral.com that is the local Phoenix paper, they have lots of great travel info. Be forwarned, it is high season at that time of year, but the weather will be wonderful. Low 90s with little humidity (like 6%). Scottsdale has a nice Old Town area, with tons of shops. There is Rawehide, which is a recreated west town, very tourity, but fun.
If you like fine dining, you will find tons of 4 star places to eat. My very favorite is Michaeal's at the Citadel, in north Scottsdale.
Hope that helps.
