Hi pam2boys, Welcome to Cruise-Chat!
Absolutely and ask away. The Members here are the most friendly, helpful, and knowledgeable of any cruise forum.
There are volumes of Cozumel information in the Caribbean Port
section. Just do a search using the "Find" tab.
Which ship are you sailing on? I'm guessing the Carnival Fantasy or Carnival Ecstasy. If you need any help just ask.
