Update: the sprint is on!

*Good news*: Facebook is covering the venue, food and hotel costs. This
is confirmed. I'm working on getting a PSF grant for flights like last year.

*Please book your* *airplane tickets* as soon as possible. Like last
year, we can reimburse up to *$500* for domestic roundtrip flights and
up to *$1500* for international roundtrip flights. If that’s not enough
to get you to California and back, let me know and we’ll figure
something out. Send me the receipts my way, you should get your money
back before the event, preferably as soon as I get the grant wired. For
sums smaller than $500, provide me with a PayPal e-mail. For larger
ones, I will need your details to set up a wire transfer. I will use
TransferWise for the latter to cut down the wire costs. * I recommend
flying in on Sunday and flying out on Saturday.*

*Please DO NOT book hotels*, Facebook is covering this, preferably in
the same hotel as close to Facebook HQ as possible. NOTE: I cannot
confirm your hotel room until I have your flight information.

Hi Łukasz,

do you have any news on the hotel?

Several attendees including me use ESTA to travel into the US. We are
required to provide Advanced Passenger Information (API) a couple of
days up front. API also include the location of the first accommodation.
As far as I remember, I have to provide the name and address of the
hotel by the end of the week.

Regards,
Christian
