So, my fiance and I are staying at the RIU Caribe in 4 weeks for our honeymoon. We've never been to Cancun. Neither of us. Not really knowing what to expect. We know we want to ride some sort of zipline through the forest, but not sure which one. Is this something we need to book in advance, or can we do it when we get down there? It is stil safe in the resort area, yes? What's the latest in the drug / legalization / war , etc. etc. etc????? Thanks.
