Very disappointed. We arrived at the zoo at 4:30 only to see all the animals being locked away for the night and the zoo keepers were asking people to leave by 5:30 and they themselves left by 5:45. If they post times from 9-6 then it should be open until 6. Especially when they still charge you the full rates....
