No, the price that I give you is the total price.
It takes me about 40 minutes to set-up a kids disco and about just over an hour for an adults disco. Packing away usually takes no longer than 30 minutes.
Yes, they most certainly are included.
I have never missed a disco in almost 25 years however in the case of an emergency, yes I have experienced DJ's that I know well and are capable of dj'ing for adults as well as entertain kids.
Well I wouldn't say I was the best on the planet but I am definitely in the top one!
