Showed up 5 minutes before start of last Saturday tour that appeared to be full. Somehow ;-) managed to land a few tickets for the family. Everyone enjoyed the tour. The check in gals were great and very helpful. The guides were nice as well. Caves and inn were awesome. Packing and beer garden were also great.
Very nice gift shop.
Cool place. Will do again next time we are in Milwaukee.
