I have a 9:20 am reservation at Tusker House on a day when Animal kingdom opens at 9 am.
Do I wait in line until the park opens for the day or would that be cutting it too close to get there in time?
I think that they may let you in early to make it in time as it is a little bit of a walk. When you get there, just speak with the CM's at the front who let in the guests with Tusker reservations.
We have a reservation at Tusker for breakfat on our upcoming trip at 10:20. So we have plenty of time. We are even going to try and ride the safari berfore breakfast.
