Thanks for the questions, and I hope you make it! Here's are my answers, happy to answer more/follow-ups.

1. Summer Camp is our name for the chill period between the two festival weekends. We've already sold ~100 tickets just for Summer Camp, so it's gonna be active.
2. SFO and OAK. You can get the Bart from SFO and then walk the last 20 mins. Google maps says that there's also public transport from Oakland (which to be clear is a fair bit closer than SFO). I haven't gone that route before, I think it might involve buses.
3. There's a few places people will be sleeping. They both have two showers that are right nearby and then there are lots more communally accessible ones dotted around campus (taking like 30-60 seconds to walk there). We'll stick a map up. 
   1. My guess is in one location it'll be 8 people for the 2 showers, and in the other location it could get to be many more people, and extra folks will need to do a little walking.
4. About 4 are one block away in our Ellsworth house. The rest are on site (mostly building E).
5. We had a 250-person event here last year, WiFi was generally fine. A few parts of campus are spotty (typically the outer edges). (We care a lot about WiFi issues and our team is down to help debug them.)

Did you see the checkbox "Only show authors confirmed attending"? I didn't understand the color coding without that, but found it very clear once I checked the box.

I've sent like 80 emails out, still tracking them all down! 

(If anyone has contact info for The Last Psychiatrist or Hotel Concierge or Christian Rudder from the OK Cupid blog, I'd appreciate a connection.)

I believe there isn't really a deadline! You just buy tickets and then you can come. Tickets might sellout is the limiting factor.

thanks for the feedback on the website. here's the explanation we gave on the manifest announcement post:

In the week between LessOnline and Manifest, come hang out at Lighthaven with other attendees! Cowork and share meals during the day, attend casual workshops and talks in the evening, and enjoy conversations by the (again, literal) fire late into the night.

Summer Camp will be pretty lightweight: we’ll provide the space and the tools, and you & your fellow attendees will bring the discussions, workshops, tournaments, games, and whatever else you’re excited about organizing.

Here are the types of events you’ll see at Summer Camp:

• Hackathons (or “Forecastathons”)
• Organized discussions and workshops
• Jam sessions and dance parties
• Games of all kinds: social deception games, poker, MTG, jackbox, etc.
• Campy activities: sardines, s’mores, singalongs
• Multi-day intensive workshops, e.g. a CFAR-style workshop or a Quantitative Trading Bootcamp (Note: these may come at some extra cost, TBD by the organizers)

let me know if you have other questions.

Both our teams (LessOnline and Manifest) are putting together big events on the consecutive weekends, and my guess is that there'll be a number of folks who want to travel for both. So for everyone around in the interim we're offering housing on-site, food, and will be helping folks run their own sub-events.

I haven't got anything to announce there yet but I have ~3 events in the early stages of being organized, all of which I personally want to attend.

We'll send out location details to anyone who buys a ticket (and also feel free to ping us and we'll tell you).

I've had some experience with people trying to disrupt events, and trivial inconveniences of figuring out the address makes a non negligible difference in people doing stuff like that.
