We paid $1500 for the dance floor. Its kind of pricey but worth every penny! How much have they quoted you?
It was $1500 for the beach reception which included the bar, set up of the tables and chairs.
It was the resort DJ and it cost $650. We had an MC and he dealt with the DJ. We just brought our ipod again with the songs for first dances and he showed the DJ what song to play at certain times. The microphone was included with this as well.
The after party at the resort disco was great. Not all of our guests went to the disco but it didn't hurt that we had a large group with us. By that time you are sooo wedding pumped from all the events earlier its hard not to have fun. Especially if you stay in your wedding dress! The disco was like being at a mini club. There are other hotel guests there of course but it just added to our fun. We also went to the sports bar before & after the disco for nachos and hot dogs.
If you think of any other questions just let me know!
