We did the combo package and our tour guide for the whole thing was Sara. She was great and knowledgeable about the animals and the caves and with a good sense of humor. It was great for our family with 2 young kids 7yo and 3yo. Not crowded. Panning for gems was a pleasant surprise as my kids found lots of nice “gems” unlike other places where it seems like just regular rocks. A little run down but that did not take away from our experience.
