It's reasonable for public space facilities to charge "for profit" space users more money to rent the space

Apparently Neal Schon of Journey who married Michaele Salahi of Real Housewives of DC fame is suing the City of San Francisco because they were charged more money ($240,000) than originally quoted ($58,000) to rent the Palace of Fine Arts for their wedding service and reception, which they then broadcast on pay-per-view.

I don't see any problem in charging the couple more than the standard rate for wedding rental, since they were using public space for pecuniary and private gain. Although they seem to have been charged more than the "standard" for profit rates listed on the rental schedule, which probably needs to be updated in terms of a three-tiered schedule (nonprofit and personal rates, businesses, and people/businesses charging people using the space).
