A mate of mine booked a ticket thinking it was for two people (he didn’t read it properly), he’s subsequently tried to add an additional person (his wife) and Busfest have told him to pay on the day for her.
Said same thing to me pay on the day , will print the email and keep in the van just incase
But reading above -
There is also no facility for any additional persons to enter 'on the day' as we must have a record of everyone on site, so all attendees must be pre-booked before arrival.
I know Busfest have been slow to reply to him, I think he had to email them a few times to get a response.
