I, as a destination wedding photographer, wrote a review/experience of our experience at the Iberostar Varadero in Cuba on the following blog which includes lots of images. Please take a look to see what you can expect if you are getting married at this resort:

Congratulations and Enjoy Your Trip! The couple I photographed said that they were advised to bring their own photographer, as the hotel photographer was "cheesy". I hope this helps!
