I have not been to mexico at all and have been thinking of traveling to Holbox next summer. Does anyone have a suggestion of how we can combine a trip to Holbox with something else so we can get our snorkel on?? We are avid snorkelers and have been to Belize, Bonaire and many places in the Caribbean, and although Holbox seeems like our perfect vacation place,nice and rustic, and quiet, it seems like ther is no other snorkeling to be had. So how can we combine two places cost effectively? Spending 4 days or so in Holbox and the same or more somewhere else? Thanks so much ahead of time for your help.
