Bay seniors reluctant to shell out $100 for a SF Ballet ticket, need to know there are cheaper alternatives. Depending on availability same day rush tickets are $30. You just have to call or visit the Box Office when it opens at 10 am ( Sat & Sun) or noon (Tues-Friday), but the deals end an hour before the performance. If your hip replacement is feeling steady, check out their Standing Room Tickets ($15-$20). And to see the Ballet, Symphony,Opera and local Theaters for nothing at all, most of their sites offer ushering opportunities.
