Hotel (yes, this info was above and I’m duplicating just in case 😃)

If we booked your hotel, you’ll get a separate booking confirmation (email title “Booking Confirmation @ Sketch & Mandatory Online Check-in”) & a calendar invite. Make sure to check in online before you travel, you’ll get a pin by email to get to your room. But here’s also hotel information:

Breakfast: please, remember that you need to order breakfast a day before, if you don’t, the hotel will treat it as if you don’t want to have breakfast and won’t serve anything. I must warn you that the breakfast they have is very light, no warm food, but on December 8 there will be also light breakfast at the venue, and on December 9 we’ll have brunch altogether :)

Here are also nearby places serving breakfast:

❗️ Some important notes

  • As you know, this event is hybrid, and we’ll have people from all over the world watching the live stream. There’s a tricky part you should know about :) In order to have as many time zones being able to watch it, we’ll start the live stream at 1:50pm CET (right after lunch), so all talks & QnAs between lunch and closing will be live streamed. The talks between opening and lunch will be recorded together with the QnAs and will be shown right after the last in-person talks. Feel free to say hi to remote audience from stage :)
  • Access Link to follow the agenda remotely on both days: – with this link you'll have access to all talks and all activities during the conference if you want to watch the live stream on Dec 8 & 12.
