The Peoria Arena in the NW Area of Phoenix has a Comfort Inn, Days Inn, Extended Stay, Hampton Inn, Holiday Inn Express & La Quinta Hotels etc type hotels.
Directly to the South on 101 is a Renaissance Marriott right by Gila River Arena but if you do not mind a 12 mile , 20 - 25 minute drive each way, my sons team (who had a blast!) once enjoyed this Hilton Resort with suite rooms and waterpark:
Pointe Hilton
Tapatio Cliffs Resort
11111 N 7th St.
Phoenix, AZ 85020
(602) 866-7500
Hope this helps!
