I had a look at your itinerary. I have some comments, the most important of which for the time being are: 1) with very few exceptions, public transportation doesn't exist in Israel on the Jewish Shabbat (from Friday afternoon till Saturday evening (working again on Saturday night)). You should bare that into account. 2) The Negev destinations you list are very interesting and recommended, but bear in mind it's a real desert (very very hot in August) and rather sparse on population and hence on facilities such as public transportation, restaurants etc. You have to plan those days carefully.
I'll be happy to go over your itinerary with you in greater depth or answer your questions. Harel 14:20, 15 July 2011 (UTC)
