We hired DJ Mannia for our March 31st, 2011 wedding at the Grand Palladium in Riviera Maya.  We had Carlos as a MC and he was great!  He met with us right before the introduction, made sure we had everyone in order and that he had everyone's name correctly.  They played everyone song as requested and the music during dinner was great (their choice of songs).  When we were running behind on schedule, they gladly made some changes and accomodated us.  They really got the party started, brought out some balloons for our guests to play with and everyone had a great time.  I would recommend 100%!
