I made the flight to Utah this week. I'll put a write up about it. The marshalling signals were pretty easy to figure out. When I taxied up by the FBO, there was a guy there waving his arms at me. It was painfully obvious where he wanted me to park and he halfheartedly motioned with his hands (no orange wands or anything) where to go. We parked right next to a really nice looking TBM 900!
The line worker got our rental car and parked it right next to our plane. It was super easy and convenient. When we left 3 days later, we only took on 16 gallons of gas, and on top of that they only charged us $5.00 for keeping the plane there for three nights. I was really impressed.
