We did the ‘Mayapan Ruins, Lazy River Tubing and Cave Swim’ (PG907) from Progresso when we were on the Disney Magic in April.
These ruins are referred to as Little Chichén Itzá. Not as impressive as Chichén Itzá, but still felt worthwhile. An intact pyramid you can climb as well as other structures to explore.
We picked this tour as it was the same length as the Chichén Itzá one, but included the cenote swimming (because Mayapan is a shorter bus ride from the port than Chichén Itzá, giving additional time for a second activity). You get to swim through a partially open air cenote and one that is completely in a cave with illuminated, very deep water you can explore with mask and snorkel. The latter was really a highlight. After the cenote there was not only a light lunch but extra time to explore the area and swim in a man-made pool.
Between the shorter bus ride and multiple activities, as compared to the other Chichén Itzá excursion, I would recommend this excursion. The enclosed cenote was the highlight.
