If this is the same Paradisus that you are referring too, I can give you all the info you need. This resort is a 5 star, and I would have very little to say that was negative. The rooms were very well kept, the grounds were beautiful, its is on (from what I'm told) one of the most beautiful beaches in Cuba (it was very nice!), pool was great, food was good - good variety in the restaurants and the buffet... Cuban ice cream - delicious! As you can tell, I could probably go on for a while about the whole trip....
I had booked 10 dives, but weather was quite windy, and blew off 6 dives. I managed to get 4 in, 3 in the same site, but it was pretty decent diving. Large grouper, crabs, lobster, plus every other Carribean fish as well... Wish I could report about the "good site", but I never managed to get out to them...Cuban dive boats are quite a bit different from anything you may have seen elsewhere.....
We did a swim with the dolphins excursion, which was a blast - a highlight of the trip. I was a little ify regarding the whole dolphin-as-a circus-animal-sideshowthing, but the dolphins actually appear to enjoy the interaction with people, and they are incredibly intelligent. Even learned some educational things too.... imagine that.
Later that day we finished it off with a sunset catamaran cruise, which was also a good time. The rum flows freely, as do the buccaneers (local beer), met people from Germany, UK, Scotland... all over - ah, except the US, and had a great time.
My wife very much enjoyed all the pampering the resorts own spa provides, and spent a couple days just chillin and doing nothing but drinking lemonade slushies.
Did a couple quick jaunts into Guardalavaca to the local vendors, and shops, tried some local quisine, cigars, rum, cuban music..... quite an experience...
I've just rambled on about some of the highlights, but if you need any specific, feel free....
