Tickets are not refundable, but you can transfer them to someone else. This is pretty common if you know a couple people from your company want to come, but you're not quite sure who. Just email John when you know who's coming and if/when you know who you'd like to room with. We'll need final names by April 30. Thanks =)
The Presentation Center is about 20 min from the San Jose airport. The center is pretty remote, so I don't think having a car will be a big asset; most folks will probably get cab or rideshare from the airport. There is an open topic for ride sharing on the forum.
While there are some single accommodations available, most rooms are shared with two single beds. If you know someone you'd like to room with, email John after you've both purchased tickets and he'll put you in the same room and send you a confirmation. You'll receive an email with your actual room number shortly before the event.
If you don't know someone you'd like to room with, we can put you in a room with someone of the same gender: just email John and let him know that's what you'd like to do.
The Presentation Center is not a hotel, so you can't make reservations outside of Pause or extend your stay on either side of the event. If you'd like to stay in the area after Pause (and surf in Santa Cruz?) you'll want to make reservations elsewhere for before or after the event.
