Learned a lot about the RESO system with guide sharing some very interesting details that would be completely missed if walking through by yourself. One suggestion for improvement might be to be more precise on the exact location of initial meeting point as I found not evident with the hotel entrance closure. Thanks for a wonderful tour.”
