I have to say that I was slightly disappointed by this tour. It may have been partly due to the fact that I was the only tourist...my guide and driver were both very friendly and did try to explain a lot. But take care that this tour doesn't necessarily take you to the monkey forest in Ubud ( I thought it did...) the one I visited was not that big and one is emotionally guilt-tripped into buying something in the local tourist shop of your assigned guide ( so somebody else who is not employed by the tour operator).
I found Tanah Lot too busy for my liking, but I think that is a personal opinion. I think that in all I just had the bad luck of being all on my own and i just missed a bit of interaction with others....
