This is what Cecilia gave me for pricing through dreams: $280/hr for the DJ, 9ft*9ft light floor $700, 9ft*15ft light floor $800. When you go through the resort, everything (individually) has 11% tax and 15% service fee- which is not included. So if you go with the resort DJ package for 3 hours, and the smallest dance floor, that's an extra $400 in fees.
You can talk down the outside vendors (pretty easily). For example- DJ mannia quoted me $300 for a sounds system for the ceremony (which is ridiculous!)- so I told them it was only $180 to get in through the resort. So they offered it at $180 (and that is the final price, no extra fees or taxes, while the resort would charge a service fee + tax if you went through them).
DJ Mannia gave me three hours with the DJ (includeds DJ/MC, DJ booth, sounds system, wireless MIC, robotic lights, white balloons, 4 cold fireworks explosions) for $800 (no extra fees). They also gave me a free bubble machine for the receoption just for booking them for the sound system for the cermony. Their light up dance floor prices are: 12ft*12ft= $600, 12ft*16ft=$800. They don't require the dance floors to be booked until a month before. Also, I am planning to get under the table lights through them because they are only $19/each, whereas they are $25/each +tax/service fee from dreams. The prices at first seem good at dreams, until you add in that extra 26%.
So if I went through Dreams, a DJ+dance floor would be $1940 total. DJ Mannia would be $1400 (and this dance floor is bigger than the Dreams one). Does that all make sense?
Hope that's helpful!
