There is no W in Arizona - never has been...though there is one being built and will be open in 2008...so not sure what the 1st person is talking about...
Anyway, are you saying "suite" hotels or "sweet" hotels? In any case, all the great hotels are in Scottsdale & Phoenix...The Hotel Valley Ho is the "in" hotel at this time. Other nice hotels are The Westin, Ritz Carlton, The Mondrian, The Hotel Indigo and The Sheraton Wildhorse Pass.
Try the Holiday Inn Express adjacent to the Arizona Mills Mall in Tempe. The place has just be entirely remolded, has a small outdoor pool, many decent restaurants nearby and is just a 1/4 mile east of the I-10 freeway and 5 miles (10 minutes) to Sky Harbor Airport. Located at the corner of South Priest Drive and West Baseline Road. Moderately priced and convenient to just about Everything!
The W in Phoenix used to be pretty nice. Also lots of suite hotels in Scottsdale.
Don't stay at the Best Western Airport in Phoenix. Very crummy rooms and service. None of the pools were working, and they were doing construction the 3 days we were there. Complimentary shuttle was NOT complimentary. Charged $10 each way. Good Luck!
try the Ritz on Camelback Rd by Biltmore Fashion Square Mall
