We just had our wedding on December 13th at the Azul Beach Resort and we hired Alex and the team at Audio Cancun to be our DJ.  We can't say enough good things about them - they were extremely helpful beforehand, based on our conversations they knew exactly what kind of music we wanted and the night of the wedding couldn't have gone any better.  The music was awesome - everybody was up and dancing (we ordered the light-up LED dance floor, which we highly recommend) - and all of the announcements were handled perfectly.  We also had a screen set up to show family photos and that worked great as well.  If you are planning a wedding in the Cancun area, we encourage you to take a long look at Audio Cancun - they did a phenomenal job for us and we're confident they will do the same for you.
