Hotel
We've reserved a block of rooms at Hotel Zeppelin for $200 a night, available Friday and Saturday nights if you book by September 5th, using the link below--as of 8/25, there are 3 rooms left. If you want to stay additional nights, you should book by contacting Cris-ann Lizardo at the hotel at 415-447-6936. While it's not guaranteed that you can get the group rate for additional nights, she will try to accommodate you if you call early and they still have rooms available at that rate. Let us know if you run into any issues (e.g., the block runs out) and we'll work on it :)
Travel Note
Airbnb is often less expensive than hotels in SF and will give you more options with regards to location.
Flight
SFO or OAK are the most convenient to the city. You can take public transit from either, but it's not an expensive Lyft ride either (and then you won't have to schlep luggage up any hill.)
