Why is Queenstown harder to book than Dunedin?
Demand and housing: the Lakes have more work than trades most of the year, and many businesses are quoting weeks out. Putting your dates and flexibility in the request is what gets a usable answer rather than silence.
How is it priced?
Usually a rate for a set number of hours, plus travel and sometimes gear hire. Ask what happens if the night runs long, since overtime is charged and is easier to agree beforehand.
Can I choose the music?
Most will take a must-play and a do-not-play list and read the room in between, which is the part you are paying for. A DJ who will only play your list is not really being used.
Do they bring the sound system?
Usually, though some venues have their own and some have sound limits or curfews. Say the venue in your request, because it changes what is needed and what is allowed.
How far ahead should I book?
For a wedding or anything in December, months. Weekend dates go first, so give the date early and you will have more to choose from.
