By the time our habits of travelling also changes. We want to be free, travel and explore everywhere without guides but on our own. If you come to Israel and do the free travelling here are some tips; you can travel on your own without being a part of a big group. you can rent a car on the airport and even a car with the GPS system. It is going to take you anywhere you want. Also, you may need internet in these days during your travel. What i would suggest you to do, try to rent a netstick which will allow you to go online whenever and wherever you want during your stay. It will allow you to have information about the places you visit. Other than that, if you have a good telephone that allows you to take good pictures than you\'re done.
My friend and I did that 2 years ago. We rented a car and had use of a GPS but it was in Hebrew so we just used maps. It was easy getting around, though it always took us longer than expected.
We were lucky to have many friends to visit and stay with and they often took us to or told us about places that we wouldn't have found ourselves.
I can definitely recommend doing your own thing.
