From the official site:
The UCLA Athletic Department is giving fans of the Bruins' men's basketball team the opportunity to choose new season seats for the best upper level seat location for the upcoming 2009-10 season in the Select-A-Seat Open House on Sunday, May 31 from 3-4 p.m. in Pauley Pavilion.
This is the third straight season that the Bruin fans have been invited to visit Pauley for the Open House and receive an actual view of available seats for purchase on a first-come, first-serve basis. Admission is free and open to everyone for this one-day-only event.
All available seats will be tagged with the price of each season ticket and corresponding donation, when applicable. Fans can process their order instantly right inside Pauley Pavilion. Methods of payment include checks or all major credit cards (VISA, American Express, Discover and Mastercard).
Current season ticket holders and fans who have already placed a $100 deposit by May 29 on new 2009-10 Men's Basketball season tickets who received an appointment time on May 30-31 should not attend the Open House.
