Agreed. You're going to get a few replies today that tell you to abandon ship because you can never rely on being seated in a reasonable amount of time. While that is true, the advice above would be mine exactly - i.e., show up a little early, ask server for your bill right after you go through the buffet line the first time and then time your actual eating time accordingly. As a buffet, you can get food as quickly or as slowly as you'd like, so you are not at the mercy of the kitchen. Safari just a quick few steps from Tusker House, and if I understand correctly, you get a 15 minute grace period on showing up to a FP late. (Do not rely on my saying this, however, as it is strictly based on seeing some other non-Disney-employee's saying it on these boards a few days ago....hopefully someone else can chime in and confirm or refute the grace period.) But even without a grace period, you should be fine.
