just find someone similarly equiped who has been there before and follow them. They will usually take a safe line and allow you to see where you need to be. MSHardiman and VXKat are good choices. When in dought just ask for a spot. There are some great spotters. Just ask around to find out who is good. Have faith in your spotter...a lot of times things look way different from the drivers seat. Your spotter can see thing you can't. And lastly if I am ever there with you... most will agree, don't follow me
As far as how long...you are welcome to come for as long as you wish. Most arrive Mon in prep for Tue VX run. Most leave Sun morning. Some show up earlier/stay longer.
