amazing how much information one can get without even getting up the couch!
thanks to everyone who replied; I think I'll follow your advise and abandon my original plan for the nonce. Lausanne will wait, I'll go either to Germany or to Zuerich (I'm still much inclined to come to Switzerland as I've never been there before and it looks just beautiful).

again, many thanks.

PS
if anyone's planning a biking vacation in Israel,or any vacation for that mattar, I'd be happy to help.
