You are the first to report that water is available at Trail Camp. That will save people a lot of time and extra fuel weight.
Your warnings about sunscreen, sunglasses and lip protection are SO IMPORTANT!
People underestimate the problems with altitude sickness. Many spend the night at Trail Camp, and wake up sick the next morning. For you and your partner, I would suggest two things: 1. Spending an extra night at altitude before starting the hike. (I like to overnight at Horseshoe Meadows one night -- 10,000' elevation!) 2. get a prescription for Diamox, start taking it the first night you camp at altitude.
You did the right thing turning back and sticking together. The mountain will always be there, so start planning the next trip.
