We got a family pass to the zoo. I have taken the kids a few times on my own and we love it. By the end of the visit I am exhausted from pushing the two of them around the 10km of trails and running through splash pads in the hot hot sun.
On our most recent visit Darcy joined us and said 'hey, lets take the zoomobile to get around, it is a lot less work!' And it really really is!
