I had my reception at Kool Beach Club and I can tell you that it was amazing. The place is gorgeous, the food is delicious, it felt completely private. Lori is right that during the day it's a very loud, busy, crazy bar, but if you hold an event there at night, the space is all yours. They provide security so that no one walks up from the beach to join the party, but it certainly wasn't any kind of issue for us. I don't remember hearing anything from Mamitas...it really felt very secluded. We had our wedding in March and there is not really a backup rain plan <---which could be an issue for you. We just crossed our fingers and our rain-plan was "well, we all get wet." I have spent a lot of time in Playa (my husband's family owns a place down there) and we took our time finding the right place. We were married in a villa and we walked through town to Kool. Obviously, I'm biased, but I thought that we couldn't have picked a better spot...all of our guests agreed. If you click to #216 of the slideshow below, you can see photos of Kool...it was beautiful!! Good luck and if you have any questions, please don't hesitate to ask! http://delsolphotography.com/blog/content/galleries/?gal=402
