Due to Covid, they set the zoo up as one big one-way walking trail. The line to wait for the train was extra long because of social distancing spacing and that they were skipping two rows on the train between each family. If you start early, you will end up at the restaurant by noon. (You don't have any way to backtrack) it is all one-way trails.
