Congratulations Dee and welcome to the forums! Im not sure if Dreams has a hotel photographer? I know the videographer is usually supplied by CancunWeddingVideo.com . They seem to do a good job and the website content looks good.
We have shot a bunch of weddings at Dreams Cancun and have slideshows up on our website for you to view what the hotel has to offer. It is a great location and very picturesque.
Best of luck with all your plans.
