Until the dust settles, three substitutes cover everything Playa Mia used to do.
For the water toys. Paradise Beach, at kilometre 14.5, runs inflatables, a climbing iceberg, slides and paddleboards under a separate pass, and publishes a pricing structure you can read before you leave home. It is the closest like-for-like replacement and it is half a kilometre up the same road.
For the all-inclusive day. Mr Sanchos, immediately next door at kilometre 15, is the island's benchmark: one price, buffet, open bar, pool, palapa. Busier and louder, and entirely predictable, which is the point.
For families who want calm rather than equipment. Playa Palancar, four kilometres further south at kilometre 19.5, is the quiet end of the island's beach-club spectrum and the departure point for boat trips to Palancar Reef and El Cielo.
If Royal Beach Club Cozumel does open as announced and you are sailing with the line that operates it, the calculation changes again — a bundled transfer and a purpose-built facility is a strong cruise-day option. This page will be updated when there is something solid to report.
