If you want to make it up to Ballarat, we have 2.

Funbugs which is near the bowling alley, indoor cricket etc and also Happy Jacks which is on the western side of Ballarat (although surprisingly Happy Jacks doesn't actually have aircon, bizarre I know)...
Yep, Ballarat is about 90 mins away so is just that bit too far. Though might head there on Code Red days and stay overnight.

Theres a play centre in Melton, just up and across the road from melton toyota. There used to be a dedicated play centre in Sunbury, but superthief auto is there now.
Thank you! Melton's not too far so we could definitely do that one.

There is on called Jungle Mania in Taoylors Lakes that ok, but a better one n East Keilor. Forgotten the name though! Jets in Gisborne is mega hot on a hot day, so not worth it if temp over about 25.

Eta you call alo have lunch at Vic Tavern in Gisborne- it has a play room, or Taylrs Lakes Hotel - in the Warergardes complex.
Thanks - Taylors Lakes is definitely doable. We go to Jets quite a bit but yep, it was boiling in there last week when it wasn't even really hot so definitely not a hot weather refuge. We should try the Vic Tavern again, haven't been there for a while. I think there might be another pub in Riddells Creek that has a playroom too but was told the food was horrible. But how expensive are pub meals these days - we went to a local with the kids last night and all up, paid $90. Happy to do that for a semi-special occasion but that was just to get out of our hot house!!!
