Last summer when DAK was open to 8 pm, on two days we went to the park as the parade was ending around 4:30 pm. We had a wonderful time. Low crowds and easy access to all of the attractions. The first night they unexpectedly closed the safari early and we missed the attraction, but otherwise these two evenings were our very best experiences at DAK.
If you can get a late evening at DAK, our family highly recommends it!
