My husband and I were just married at Le Blanc Spa Resort in Cancun and DJ Mannia provided the DJ service for our reception as well as a light up dance floor (THE BEST PART!!)  I had booked way in advance and the communication was very easy, I was slightly nervous since we had just communicated through email and wasn't exactly sure what to expect when they arrived, but trusted the excellent reviews they received on the website.

About a month before the wedding, I asked them to add a light up dance floor for 50 people to the contract, which they did with no problem.  It was the best part of the wedding and all of our guests are still talking about how much fun it was, definitely worth the money and the best investment we made!! 

I sent the DJ a list of songs I wanted played during dinner, the reception, and first dances.  When we arrived at our reception, he had already set everything up (and even moved the DJ booth inside since it had showered for 20 minutes prior and wiped off the dance floor).  I spoke with Matt about what song we wanted for our entrance song (which I hadn't specified before), the order of people, and who needed to make speeches (and when).  He kept everything on time, since I was very specific about wanting to get to dancing asap.  

They did a great job mixing songs (old and new) for everyone to be able to dance to and in a good order. I know everyone really enjoyed the music, dancefloor, and party.  At one point they even brought out balloons to dance with, other props would have been cool but I'm assuming you probably have to pay additional for that, and we already had maracas.

DJ Mannia had already been to Le Blanc before, but I put him in contact with my wedding coordinator a few weeks before the wedding and they worked everything out in terms of what time to be there and where to go, so I didn't have to worry.  My only con is that the resort I had my reception at now has outside vendor fees, so if I had booked a year later, I probably wouldn't have been able to have DJ Mannia at the reception.

Please let me know if you have any questions - I didn't do too much shopping around with prices, I saw great things about DJ Mannia and booked them, so I'm not sure how they compare, though I did shop around for the light up dance floor and they were cheaper than the design company that did the rest of the decorations at my reception.  I was very specific about what I wanted and the songs at my reception and DJ Mannia did a great job of delivering good service, I was overall very pleased and would recommend them to anyone!
