My husband and I planned our wedding at the Excellence Riviera Cancun. we knew we wanted our wedding reception to be one big dance party, but neither of us are very good at picking music.  We were reluctant to use the DJ because of the cost, but it turned out to be worth every penny.  The DJ played all the requested songs and music genres.  We had several guests comment on how great the dinner music was.  We did not select a first dance song and had the DJ pick one and it was perfect.   Once the dance party began people who didn't like to dance got up and partied.  He even played an extra song at the end of the night.  We could not have been happier with our experience.
