You pay the same price as you would for Marwell Zoo or Arundel Castle, but you will have seen it all in less than an hour. The interior is shabby, the toilets by the otter area look like they were plumbed in the 70's. The otter area literally stank, there were a lot of people making a b-line for the exit after catching a whiff of THAT enclosure. My advice to the unwary traveller is that this is not the mainstay of your plan for the day, rather a back up for bad weather.
