I am not familiar with Kids night out.
But if you are looking for babysitting/kidsitting type info -
Last year we used the Cub's Den at WL when DH and I ate at the Artist Point. My 2 DD loved it. They got their own dinner. Played and watched Disney movie. Didn't want to leave.
This trip we have Cub's Den booked again plus we are going to try Simba's Cubhouse at the AKL when DH and I hit Jiko's.
Have fun!
