it seems to be 3 groups of participants:
a) coming just for one day and join the group
b) coming over the weekend
c) staying one week
to start asking for possible locations I ´d need to know who belongs to which group
I would try to fit group c) then to a pension and if necessary one or two houses directly beside
group b) to which I belong might fill, if there is space or go to a hotel, as pensions do not really want gueste only for two nights
group a) just gets a short info about location and time in advance
about a car rental: as I can only stay friday till sunday, might boost it to monday morning, it would be better to rent a car with the driver beeing there the whole week.
I will for sure support and help you to make a nice program for the week. In case you fly, I suggest to deccide about Zürich or Friedrichshafen, rent a van over there and come togehter.
Let´s first see about the groups sizes. Then I will figure out space and prices and let you agree or disagree.
How do we decide about the program? For the Mainau island a booking is mandantory, for other places I have to find out and it depends on the group size if it makes sense. A city trip to Lindau, Konstanz or Bregenz makes more sense in a smaller group with one or two cars. With the weekenders we can visit Meersburg with the bus or Überlingen by ship
@ admins: either everybody mails me about the stay or you make an official list where all have access and we can work as well on the program in it....
