Thanks Everyone we had a brilliant day!
Took most of the advice. We went straight to the boat and got to feed the sealions which was definitely a high point the children loved it!
We had a picnic at lunch which was a bit waspy but ok.
After lunch we did the safari and saw everything even though most animals were asleep because it was hot.
Then we went back to the walk around park and saw all the animals. Couldn't feed the Lorikeets but went back later and we did.
We did the hedge maze in 20 minutes DD10 took the lead and is a pro!
After that everyone was a bit hot and bothered so we went to the little farm, sat in the shade and had some water. Looked at the turkeys. DS4 saw a donkey do a poo and all the other donkey ate it, definitely his high point!
Then we went to the railway, gift shop and ride on rhinos and lions. We finished with the dinosaur animatronics which was fantastic.
Finally at 7.00pm we walked our exhausted selves back to the car, got out a plate of picnic things for each child to nibble on the way home and left.
It really was the perfect day so thank you all for the recommendations I have no doubt that it made all the difference (especially when we walked past the queue for the boat in the afternoon and it was literally 10 times longer than the morning queue!)
