I just got back from my wedding at MDC...and let me tell you, it was amazing! The staff is fantastic, and they pulled everything together for our wedding for us perfectly. We didn't have to worry about anything at all. I actually used Rashel Edwards who is one of the best makeup artists on the island for my wedding, and she did an awesome job (she does airbrush which lasts all day). A few of my bridesmaids used her as well for hair and makeup, and some of them used the Kamala spa for their hair. I can tell you that the up-do's that Rashel and her team did, did last longer than Kamala's (which lasted all night), but Kamala also does great work, at a very reasonable price.
Hope that helps! Good luck with the rest of your planning. Trust me, you're wedding will be fantastic at Moon Dance!!
