In March it did not open for EMH. It was EMH 7-8 and safari opened right at 8.
But you CANNOT trust MDE! It showed a 10 minute wait time during EMH, but when you got to the entrance CMs were there with ropes. I got on the second truck to leave and you could tell a lot of animals had just been let out (African wild dogs running around getting their scents on everything, Giraffes all collected in one area eating).
