Did you know that there is a secret entrance to Animal Kingdom? When you arrive at the parks and the turnstiles are crowded, duck into the Rainforest Cafe (it has an entrance outside the park) and head through the gift shop. Just outside the exit doors to the gift shop is a semi-private turnstile into the park.
Since Rainforest Cafe opens at 8 am (Animal Kingdom usually opens at 9 am), you should be able to use this turnstile at rope drop. Due to it’s position into the park, that could put you ahead of the masses so that you can beat them to the Kilimanjaro Safaris.
