Vectis...if your son's ticketless friend has no luck, then the plastic wristbands do have a bit of give in them, and with a touch of gentle persuasion and a disposable lighter they can be eased over your wrist and niftily placed on someone elses wrist.

So if they are planning to plot up for the weekend then they should all be able to come and go....Just not at the same time, but time back at the tent/van is always a welcome break too. Put kettle on.
