Like everyone else said, mornings are the best.
We did the special AKL tour last year that happens first thing in the morning before the park opens.
Now the truck stops and the guide talks abouts stuff, so the trip takes over 45 mins, but we got to see every single type of animal except one. It was some kind of antelope, I can't remember anymore.
The point is, we never saw that many animals, even when we got on first thing in the morning. And with Main Street USA's statement, I suspect that with his and my very early morning experiances...the earlier the better.
BTW, we are doing the AKL Sunrise Saffari again this year...I can't wait! :sohappy:
Have fun!
