Looking for a new vacation experience that includes two children 22 and 18. In the past we have been all over the Caribbean and Mexico areas of Playa Del Carmen and Cancun. A friend suggested Costa Rica so I am asking for suggestions. We want beach, snorkeling, and space in the accommodations. Any suggestions will be great. All-inclusives would be nice if available. Budget not set yet, it depends on what is of interest. Please give me your advice as I continue my research on this site.
