From the Suns official website:
"Fans will receive their first public opportunity to catch a glimpse of the 2011-12 Phoenix Suns when the team hosts a "BIG Things are Coming" Open Practice on Saturday, December 17 at US Airways Center. The event will begin at 4 p.m. and is open to the public free of charge.
The Suns are encouraging fans to donate a new toy upon entry to the event, benefiting the families of St. Joseph’s Hospital. While all toys are welcome, those for children age 9 and older are especially needed. Fans who donate will be entered into a raffle to win autographed Suns items and merchandise at the event."
