There were enough animals for them to see, but not too many that they were bored by the time we had been there five minutes. Obviously we didm;t pay but it would have been really reasonable which is another major plus.
Ava loved the animals especially the horse. While Esme screamed whenever an animal made a noise and wanted to be carried like the princess she is. I suppose that is what happens when you live the majority of your life in London hahah.
