I agree completely with Ace, but just to add: I'd aim for Grindelwald First
on the quietest day, which for you I guess will be the Friday, if you
really want to go there. But you don't have to go there at all; there is
more than enough to keep you happy at Kleine Scheidegg/Maennlichen (above
Wengen) for two days, and Muerren for another one.
