I was there for the full term. As for "busses for staff", that was only the last couple of days, they didn't give notice, and when word finally leaked out, the busses were high above Echo, so you had to climb up to meet them. Hardly worth the effort. It would be nice to have such service, but hardly a deal-breaker. I lost 2 inches in the waist and gained 2 pounds during the event. Went in overweight - 25.0 BMI, came out even more so. Long walks and great chow - except for lunch, which I can't call "lunch", it was more like a bit of munchies. My venue was well staffed and quite successful. We did have problems with the rain and mud, but we coped. Cold showers were nice on the couple of hot days, but tough the rest. But we handled it. (Solar bags were useless, as the water was cold again by the time we were ready for nighttime showers.) I went through 2-3 shirts a day, as the up and down two-mile hikes to work in the humidity did lead to sweaty attire. Thank goodness for the laundry service! The cot was really comfortable, and the 4-man tent was adequate - better than I expected, but that has a lot to do with great tentmates.
Will I do it again? The jury is still out. I'm already in my 70s, so it will depend on my physical fitness in 4 years.
