Going to Playa del carmen from Valladolid by Ado, we like to make a stop in Tulum to see the ruins before taking another ado bus to Playa del carmen,our stop for the day. Is there only one Ado bus station in Tulum? When we arrive in Tulum, we will need to leave our suitcases at the bus station lockers, is that safe to do so? We'll problably get a taxi to the ruins, how far and how much would that be? Is it easy to find a taxi from the ruins to get back to the bus station in town after the visit? How early do we need to get to bus station before the departing tim in general? Can we purchase ado tickets in advance in any ado ticketing points for other departing destinations in general?
