Professionally guided tours of the Lower Loop of Yellowstone National Park

Our tour guide's name was Hannah and she was very nice. She said she had just started with the company not that long ago. We liked the fact that we were picked up @ our hotel so that we did not have to worry about which way was the correct route to see Old Faithful and that lunch was provided which was fresh and good. My complaint would be that I am not sure if it was the training or lack of which maybe with so much information to remember it just was not that smooth. We would ask her questions and she was not sure and said she could google that. She would point to things on the right but said they are on the left. Confusing. Communication was not strong either as to where to meet and how much time did we have to view Old Faithful. This is important since there are so many people there and I do not have her cell # in case we could not find her when she was parking the van. For $220.00 per person I expect the tour guide to at least have a basic concept of Yellowstone and here is a suggestion to maybe have a cheat sheet nearby to refer to. I understand everyone has to start someplace but she really needs to study up more of the information of this beautiful destination. This was on my bucket list like I am sure a lot of people are and kind of expensive and I feel we got cheated on the tour part of really learning about Yellowstone. We did tip her but felt we wished we had more of a seasoned tour guide.
