Do you know of a nice chalet to rent (very) near Interlaken to host 25?

I don't want to destroy your illusions but rather tell you what it's about with a "chalet". The Swiss (whom I'm one of) consider a chalet to lodge between 2 and maximum 10 people. So, what you're looking for is simply a house. I recommend to contact the local tourism bureau, they list all available rooms, they also speak any language (including English). Go see their website(s), they show all necessary contact possibilites (a href="http://www.interlaken.ch/index.php?id=53&L=3" rel="nofollow"http://www.interlaken.ch/index.php?id=53…/a and a href="http://www.interlaken.tel/)." rel="nofollow"http://www.interlaken.tel/)./a Be advised that especially in summer, the area is full with zillions of tourists, therefore, room/house reservations must be done well in advance - which means, right now. Additionally, be prepared to hear that for only two nights, houses are not very readily rented out (rather than for an entire week)
