Took a taxi to Chankannab National Park. Noted that the taxi rate had gone up since last visit to $11. Park entrance with snorkeling gear / souvenir t-shirt / drink was $37/person. The park was unusually not crowded as Triumph was the only ship in port (which seemed odd for a Thursday). As such, the employees of the park were more aggressive selling things like guided kayak tours and massages. The park had also added some new things since our last visit - zip lines (not yet open) and a crocodile exhibit. Being Mexico, the zip line ran rather close to the crocodiles!
Just took the bus into town and walked along the beach. Didn't partake this time, but you could get a 30 minute beachside massage for $10. Will probably do this when we repeat the cruise in November. The beach was "better" than I remember, along the lines of Galveston. Noticed lots of police in the area, especially cruising along the road beside the beach.
