We just got back last night from our first trip to Coz - had a fantastic time. And we stayed at El Presidente. This is a beatiful hotel if you have a lot of $$$ to spend - but we think that next time we go we'll look for something much less expensive, like Caribe Blue, ScubaClub, Hotel Barracuda, or any of a number of other choices. After all, we ate most of our meals in town and away from the hotel, so we just needed a comfortable place to sleep each night. Despite a little wind last week we managed to get in 8 great dives with excellent viz (100' +) on 7 of 8. We followed the recommendation of other SB members and chose Blue Angel as our dive op - I know that there are many other excellent dive ops as well. Water temp was a balmy 79 degrees - saw more kinds of fish, coral, sponges, and invertebrates than I can list. [I'll be downloading some pictures that I took as part of a larger trip report within the next couple of days]. As relatively novice divers this was our first experience with drift diving, and we really enjoyed it. We'll be back to Coz again before long, maybe in July as part of a trip to Holbox (spelling?) that we are contemplating to check out the whale sharks.
Oh yeah, I head great things about the Caymans too, but having no first hand experience, cannot comment either way.
