My husband and I just returned from the Jan. 30 sailing. We went to the Tulum Ruins tour. If you like ruins and enjoy history, the tour guide was extremly knowledgeable, informative, and humorous. If you don't care much to hear history, you might not enjoy as much.
It took a while to leave the ship, as we were waiting for the ferry to come to pick us up @ the ship. Then there was the ferry ride to Playa del Carmen, then a 15 minute restroom break at a gift shop area, and then a bus ride. Once you arrived at the location, it took a while for a collection of money $2 rountrip/person to ride the tram (save time from walking 900 yards)to the ruins. We were only able to spend 1.5 to 2.0 hrs. at the Tulum ruins. There are some gift areas outside the ruins as well.
If given the opportunity again, we would probably not do this tour, since we spent less time at the ruins, more travel time than expected. It's a good tour, but there is too much travel time involved. Hope this helps.
