Just got back from Israel, and saw (and used) the signs for the trips to Chevron and Kever Rochel. They have it every Monday and Thursday, and it leaves at 1:30 pm from 11 Yechezkel Street near Kikar Shabbos. Depending on the crowd, that's what your vehicle will be. If more than around 10 people show up, im assuming he will bring a bus, less then that and he will use a tender like by me. Should only 2 people happen to show up for the day, he told me that he will just take you in his private car. The price is 100 shekel per person, and he goes to kever rochel, Me'aras Hamachpela, kever Yishai & Rus, as well as the Jewish Cemetary in Chevron. The smaller the crowd, the easier it is to get a agreement how much time to spend at each place. Im my case, we all decided to skip the cemetary there. His number is 050-417-1979.
(P.S. Dan, I think you should rename this thread the CHEVRON, ISRAEL, MASTER THREAD)
