While taking to some people, we realized it is better to publicize more that due to our requirements to pay for rooms and the shuttle buses in advance, we need to know what is taken and we should give back the unoccupied rooms to the hotels. Otherwise we would need to pay for their reservation even if not taken, which would be a risk our budget is not ready to take.
So make sure that if you intend to take our help in finding a room, then register for Drupalcon (only €120 for a ticket) and book a room on our website within two weeks from today (by July 24th). Same applies for shuttle bus tickets. We are going to make up a shuttle bus schedule shortly based on the preferences of those who signed up for tickets, and will refund money for those, who found that the final shuttle schedule will not fit their needs.
Also, if you booked a room but would share with someone else, please ensure that you get your roommate in by the same deadline. We will send over the list of people taking rooms to the locations. Those not specifying roommates might have issues if they show up with roommates, so make sure you set this up properly. (Create an account for your roommate on the website and get her specify her name in her bio to be able to specify her as roommate, if not a registered Drupalcon attendee).
That we need to end the room service is not the end of the world though, since it means that several rooms we pre-booked will fall back on the locations, and we will keep up a page with contact information for the locations we had previously, although we cannot guarantee that they have the space for you or you can arrange your room with them. Those not going with the shuttle will find the train information handy on the travel page.
