first time cruiser

Thank you all for the information....I set sail Saturday and feel better having read your input!

Thank you so much for the information!  This is very helpful.

Hello all.....I'm set to sail on my first cruise in a few weeks visiting Costa Maya, Belize City and Cozumel.  I'm not really interested in touring any ruins --- did that many years ago in Mexico --- nor do I think I want to do the cave tubing in Belize.  I think I really just want to be on a beautiful white beach looking at clear blue water.  Is it worth booking a beach excursion through Royal Caribbean or is this something I can simply grab a taxi and do on my own?  Suggestions?  All advice is welcome and will be appreciated!
