Hi Lee,
Welcome to the board! First of all, don't believe everything you read. Some people are impossible to please, and in terms of reviews- good news travels fast but bad news travels 10 times faster! What I mean is, people only tend to post the bad reviews, but think of the thousands of people who stay at these places and have a wonderful time, but haven't posted a review.
I also read those reviews and get totally scared from time to time, but have to remember my site visit and how wonderful the resort was while we were there.
While on our site visit, we stayed at Riu and visited Dreams, both are lovely resorts. If you are looking at April 2007, it may just be a matter of which resort having an opening because a couple months ago I know that availability was extremely limited for both places.
Good luck and let us know how else we can help!
