With those time, I would rope drop the park and ride FoP standby, then head to the safari or another ride you'd want to do, breakfast/lunch at 10:35, then head to your FoP FP. You have until 12:05 to use the FP.
Many recommend 90 min for an ADR. Idk how big your party is but when my wife and I eat it's usually not longer than 60 min. I'd show up for the 10:35 ADR around 10:15/10:20, hope to be seated a little early, then be leaving there at about 11:30/11:45. By the time you leave the back trail from near Lion King to Pandora should be open so it's just a short walk from Tusker House.
The system will let you in without a CM override up to 15 min past your FP window. Anything after that it's up to their discretion. I think you could be in and out of Tusker house in around an hour. This would allow you to get 2 rides on FoP that day with minimal wait
