Thanks for the trip report. Yes, it would have been better if you had acclimated another day up at elevation, but it is good that you listened to your body. On my first day hike, we supposedly had a runner come up the day of the hike but we never saw him on the trail because he developed altitude sickness around Trail Camp. Almost half of the trail is above 12,000 feet, and that is what makes the hike interesting for first timers.
