Cozumel in December

[white cap]

Hello, we are doing a Princess cruise the middle of December.  Looking at an Open Top Tour Bus and Beach Club tour.  Anyone done this tour?  A bit concerned that it might be too hot riding around in an open top bus for several hours..... Any thoughts about the weather in December or this tour would be appreciates..Thank you,

Cozumel in December is amazing. It isn't usually hot at all.  If a Norte can come through it gets chilly (enough that the locals are in parkas, and I'm glad to wear jeans instead of shorts).   Couldn't tell you about the tour. When we are in Cozumel we spend our days underwater and nights at restaurants.
