Marcia, I've been checking out the Divi and the Ren to have my July 2010 wedding..The Divi if you stay ,is half the price of the Ren for the wedding, but Ren Island is just so beautiful!! We spent every day over at the Island and didn't see one bug...
I've stayed at the Ocean Suites and loved going over to the Island during the day. We didn't think the rooms had any odor. The one thing I did not like about the room was the view of the Parking lot from our "ocean view" room..

The pool on the other hand was awesome on the Ocean Suites side. They have a swim up pool bar and the bartenders are great!
We checked out the Marina side and found it would be great for people who like a lot of action. It was very load with lots going on in the pool area.
I got price quotes from both the Divi and Ren Island so let me know if you would like me to share.
Thanks
Andrea
