Defintiely not an ordinary tour
You're right craz, they are not an ordinary sightseeing tour group, as they are Jerusalem based but seem to serve primarily American church groups. The value seems good - 6 nights in Nazareth, 4 in Jerusalem with all lodging, meals and ground transportation to/from TLV as well as day trips, all for US $1,331. I would book my own overseas air separately and travel that part of the trip as an individual.
I have not been to Israel since the 70's, but this seems like a very good buy (assuming I can get through security at TLV with the Afghan visa on my passport). Is that impression wrong? The trip was recommended by a friend who went on a similar trip with Sabeel last year, sponsored by her church. But you don't have to be a member of any church, or of Sabeel, in order to participate in this trip.
