OE has stated that if you want to camp together, you must go through the gate together. there will be a waiting area supposedly so that you can wait for your camp mates.
i believe this year will be a bit more organized but we shall see...
I will be arriving in flagstaff on Wed, got a hotel in Flagstaff and will be entering OE on Thursday at 8am, I have work Thursday so getting camp setup will be a priority for me.
