We were there almost 2 years ago (Aug. 2002) and thought it was very interesting. It was VERY hot that day and it was the last day of our trip so we were a little tired from the previous days but I would go again if I had time in my schedule. This year we don't have time so we won't be going.
There isn't much for younger children and that was a problem for us since we had an 8 year old and a 3 year old but they enjoyed seeing the animals (camels and donkeys, I seem to recall).
The performance of the crucifixion and resurrection was incredible.
