We just got married at El Dorado Royale on June 16th and we also went with the DJ that was offered through Lomas. They emailed us a music spreadsheet where we listed a lot of songs we wanted him to play during the reception (mostly hip hop & R&B along with specific songs for the first dance, garter & bouquet toss etc. We were VERY HAPPY with this DJ. He kept the party going all night long. We never sat down once the entire time. The DJ also had glow sticks & balloons which were a hit! Luckily we saved $500 by providing our own MC so I can't comment on that part but other than that I think you are safe
