In my opion We used Playa Azul for the reception - it was perfect. It's far down the beach so you don't get as many gawkers. I saw lots of weddings at Playa Coral, and while the backdrop is gorgeous - it seemed very "in the middle of things". They would block off the sidewalk for brides to walk down the aisle, and you'd get a back log of people waiting, and walking by. You can still go take pictures on the rocks at Playa Coral after your ceremony, my sunset photo is there. During the evening, I found it was always busy at the Coral beach too - as its right beside the restaurants - however you're usually not paying to much attention to them. It is also a smaller site - if you have a lot of people. I originally was going to have both at Playa Azul - the reason I didn't was that everyone was staying at the Palace, and it's quite far from the hotel. We were at Playa Palmerus and it was fabulous - we forget things in the room, people got cold and wanted sweaters - and it was a 5 minute walk away. Photos are in my planning thread if that helps. In my opinion, it was nice have the ceremony further away and more private, then be closer for the reception.
