It's pretty close to Downtown Berkeley, CA. You'll get the precise address after you purchase a ticket.

Opening session will be Friday evening sometime in 5pm to 7pm. You can arrive any time on Friday you like though.

The weekend will be filled with talks, workshops, puzzle-hunts, dance parties, and late-night conversations around the fireside.

Would you like to run a session? After you've gotten a ticket and we've processed it (takes about a day) you can submit a session on the schedule.

Here are the sorts of things we'd love people to run:

• Debates: Present arguments for a claim that you've thought a lot about, and argue against someone who disagrees with you about it.
• Storytelling: Read us a new story that you've written.
• Workshops: Give a workshops on a skill you've had practice with — statistics, forecasting, investigative journalism, story-writing, anything you know well and people might be interested in.
• Talk with Q&A: If you have talks you've given before or have one you'd like to give to this audience, we'd like to hear it!
• Memo Sessions: This is where someone has written a short essay (2-6 pages) ahead of time, then a small group of people reads it, and then has a Q&A with the author about the ideas in the essay. It works best if the author defends a strong or surprising claim that some people in the room will clearly disagree with.
• Make music: Bring your instrument and have a jam, or lead a singalong, or host a dance session.
• … Something else?

Over the weekend, there will be a continuously updating collaborative schedule for sessions that anyone is invited to add to.

We don't know yet, but you can register your best guess in this market! (Note that we have 270+ people with tickets at the time of writing.)

$500, minus your LessWrong karma in cents (minimum $0). This includes breakfast, lunch and dinner. We also offer housing and childcare as add-ons.

After clicking "Buy Tickets" below, you will be taken to a Stripe payment page. When you get there, do the following:

• In the field "LessWrong Username," write your LessWrong username.
• Look up (on LessWrong) your karma. Multiply this number by 0.01 to determine your discount. (So, if you have 613 karma, your discount is $6.13.)
• On the payment page, click the "Change amount" button beneath the listed price.
• Subtract your discount from the price listed. (So, if the listed price is $400, and your discount is $6.13, you should change the amount to $393.87.)
• Click pay!

Absolutely! Kids tickets are $50 (ages 2-10). Kids below that age come free.

We can support people living on-site with their children and you will be able to pay for daycare for your kids during the event.

Sure! As much or as little as you want. If you're coming just for one day, you can buy a day pass for cheaper than the full ticket.
