Has anyone ever booked an excursion in Cozumel through the company shoretrips? We're thinking about a beach excursion that sounds fun but they won't tell you what beach it's at.

Shoretrips is an excellent company - I have used them numerous times. If you go to the "Contact Us" section of their web site they provide a toll-free phone number. Someone from the office will be able to give you more details about the specific beach and if they do not know they will find out.
