The Zoo made a statement that said: "We don’t want to turn anyone away from enjoying the Zoo whenever they want to visit." Zoo officials also said visits to the legendary institution will remain free of charge.

The Zoo will release a limited amount of reservations approximately one hour prior to posted opening time on sell-out days to best accommodate guests unable to secure advance reservations.
