3-day Pass vs. 1-Day pass & Camping

[svlotus]

my partner and i are driving our camper to set up thursday night and then plan to return after work on friday for the full weekend.  I have three other friends who live in boulder and are coming for Saturday only and are not staying the night with us. 

my question:  how policed is the onsite camping for festival goers without the 3-day pass?  i was a wee bit confused when i bought the festival pass and vehicle pass and assumed my friends could hang with us at our site throughout the day.  i hope this is the case.

cheers!

Anyone in the campground(s) is required to have the appropriate campground wristband.
