My husband and I stayed at the Royal and used the most fantastic tour company. We went on a bus to CI, a cenote, and lunch was included. The tour operator was an archaeologist and anthropologist, spoke 4 different languages and provided the most interesting tour we have ever been on...problem is we don't remember the name of the tour company. We are returning and cannot stay at the Royal because we are bringing our teenage boys and we are not staying at a REAL resort. Any input on what company this may have been or recommendations for a superior tour company. Our itinerary will include swimming with the whale sharks and either Tulum or Coba.
