The guide was terrific, however, the actual cave tour was disappointing. It was more like a tunnel than a cave, and it was mostly just crawling through the tunnel with not much chance for photo taking.
The guide was friendly and jovial, however, the trip was slightly marred by a 1.5 hour delay from 6-7 of the participants being lost in the cave. Certainly not a trip one will forget, but perhaps for the wrong reasons. The ratio of participants to guides was far too high, and I would choose to go on a trip with a maximum of 8-10 participants going forward.
