Interresting how many more people got interrested as Monta comes. Anyways, I'd guess that there aren't so many people who are going on vacation at that moment, so unless every one else could come a week later, lets stay to 15th to 20th july. Copenhagen is the place no matter what. Peter and Tobi can have people at their houses, but I'm not sure how many. So maybe some one has to stay at a Hotel.
