Tubing was 3 hours. But if you go early enough they'll let you go down twice for the same price but make sure you have lots of sunblock because you will get burnt!! The shuttle ride was only about 5 10 minutes. I'm not sure about the location you're asking about, but we weren't in the shuttle very long at all.
There is no shuttle service to Phon D. Shuttle service runs between Water Users rec area, Pebble Beach rec area, and Goldfield rec area. There is no service past Goldfield.
