I Live near Hungary (Slovakia), so it isn't a big trip to came to Budapest UDS. But I don't know who can attend this event. Everyone? Or just the community members? Is it needs to register somewhere? And if I haven't rent a room yet, can I rent it the Grand Hotel (how much it is?), or it is only for members?
UDS is an open event and everyone is welcome.
The travel page has a form where you can contact the hotel and get a discounted rate. We do ask that you register though so we can get an accurate headcount for food and so on.
Hope to see you there!
That's a really good question. I'm pretty sure anyone can come, as long as you register (at zero charge.) You can stay at the hotel if there is a room free, or there are some other option.
