Anyone dove here?.....The Cavern ¨CENOTE¨ diving in the Riviera Maya in Cancun http://www.mayanaquadive.com/cavern-diving/cavern-overview/ Is it worth the trip? Anyone dove Cancun that would recommend a particular dive operator? My sister-in-law was asking me and I?ve never dove in Cancun and have no idea if it?s a good place to dive?.or just so-so. And she asked about these caverns. She?s a newly certified diver, but it doesn?t look like they actually penetrate the caverns as much as just swim by and look into them. Any thoughts or comments? Thanks!!! ~Leigh Ann
