@@barbiebec not a problem!
We had a couple groomsmen pop in to Playa and pick up a couple bottles of hard liquor, spent less then $100USD and the hotel served it.
We used their DJ, he was great! He can hook up any smart phone for your specific dance songs, other than that we asked him to play top 40 and then I requested a couple country songs and he had no issue playing them either. With that rental you get a microphone so our MC ran things like a regular wedding. Speeches, announcing first dance/ father daughter dance etc.
It went really well and we were really happy. We were dancing the night away and had many people looking in the glass door and even trying to come in and join.
The only downside is that there are no bathrooms directly in the Ibiza gala room. The room next door is the 24 hour sports lounge so we popped in there to use the bathrooms.... and my father in law snuck in there for hockey game highlights haha.
