Longtime reader, first time poster here.
GandC, my wife and I (both mid-40s) summited AMS-free a few years back with a reasonably similar plan. We spent six nights averaging about 8,500 feet, then headed up to Trail Camp for the night before our summit attempt. We got a bit higher on day hikes (Mt. Dana - 13k, and Mono Pass - 12k, but didn't spend much time at peak elevation). Bottom line: We moved noticeably slower than our usual pace, but we summited with absolutely no symptoms of AMS. Neither of us had ever been much over 11k previously, and my wife had backpacked only once prior, but we both felt great. We drank and ate small amounts frequently, and took 600 mg of ibuprofen before leaving TC. I imagine that helped as well.
As said elsewhere, your mileage may vary, but I'm guessing you'll be in better shape AMS-wise than most. Good luck!
Thanks Dave, I appreciate the story and words of encouragement. Welcome to the forum!
