As an overseas visitor, EMH in the morning are always great. I can't stay awake long enough to take advantage of EMH at night. (I'm a wimp, I know!)
That aside, I always thought that the hours at AK were shorter because of the animals. I cannot remember exactly what was said, but there seemed to be an indication that long hours stressed out the animals. Anybody else every hear that?
If that is indeed the case, they could always close the Safari early and just leave other rides open. Just a thought.
