My baby will be almost 2 when we go on our cruise that is stopping in Castaway Cay and Cozumel. I'm obviously not worried about excursions in Castaway Cay because we will just have a beach day but its been a while since I've been to Cozumel and am wondering what kind of excursions would be a good fit for our family. I'm big on car seat safety so if we do an excursion, the only way I would feel semi comfortable is if we were on a very large transit type bus. Anyone have any advice? Beach days or other baby friendly excursions that transport in a very large, enclosed bus or ferry? We are also open to experiences around the port within walking distance. Thanks in advance.
