24 May is nothing but "arrival day". I haven't planned anything other than getting people settled into that home and maybe dinner for all in the "Bistro". Sunday is for adaptation, getting over possible jet-lags, so all we shall do is go to the swimming pool (which is both indoors and outdoors pool, with restaurant and all.
The real "sight-seeing" (Hamburg, Lüneburg, Bremen, canoe trip) will only start on Monday.
So it depends on what you want to see and do!? Do you think just meeting us (and seeing my highly uninteresting "town") is enough? You decide. Should you plan to make use of the camp site, let me know, I might need to inform them in time!
And I have counted and came to the conclusion that the apartments are filled with 16 persons (given DigitalDiva+boyfriend and also photojazz really come!), maximum is 18. But there are always more possibilities, also cheap or for free even!
