We were looking for our tour guide and got lost trying to navigate the busy park, we asked for help from a worker of the parking garage and they directed us to a current tour. We slipped in the back and waited until they were moving on to explain what happened. They were extremely nice and even offered to have a join a later group so we could enjoy the whole tour. We decided not to and continued on. Toward the end of the tour we realized this was the wrong group and spoke to one of the host again she checked our tickets and told us we were following a different company and had not paid for this tour. We felt terrible and apologize profusely but she was so gracious and said not to worry and invited to finish the tour with them since we had already missed so much of our paid for tour. We were very happy. They provided great stories and answered questions they were so very nice we are very appreciative. We look forward to actually taking the tour ASAP. Thank you for being so nice and understanding.
