If you have family here ask them to do some research on the play centres. They charge for entry which ranges from around $4-$7 depending on how good they are and the childs age. We have a fantastic one in Scoresby which is too far away from where you will be but it has everything you were after and the best part is it's great fun for the adults too. There are alot around, maybe google it too. We spend 1/2 a day a week at the play centre in winter -it's a good work out for both of us! The other thing is there is a company called playtec, look them up on the web and perhaps email them and ask if they have fitted out any play centres in the area you are after. Have a great trip.
