We had a real long queue to get into the zoo and it was real hot too. Once inside the animals had real big enclosures which meant you could not see very many of them and there were long long walks between each animal. There was a little train to take you to each section which cost extra to the entrance fee.
We did notice that parents with young children had carts to pull the children around in because it was a lot of walking.
As long as you know and are prepared for the walking it is a fun day out.
You need to go back to see all the animals.
