The Edwardian Ball San Francisco Venue
The Edwardian Ball in San Francisco is held at the Regency Ballroom on Van Ness. Built in the Edwardian Era, in 1909 and done in beaux-arts style with 35-foot-tall ceilings and 22 chandeliers, it's an elegant backdrop for a fun party.
Crowd Factor at the Edwardian Ball in San Francisco
In San Francisco, it's not unusual for a long line to form outside the door, especially before the party gets started. Veteran attendees say you should arrive about hour before you actually want to get in.
Parking is also somewhat difficult near the venue and if you plan to stay very late, be sure the lot you choose will still be open when you're done.
What's Special at the San Francisco Edwardian Ball
Because it's the original, the San Francisco Ball is better-attended and long-time attendees have had more time to perfect their costumes and because it spreads over two days, there's more time to enjoy it.
