Bag Policy Large bags including rucksacks are not allowed. There are no facilities to leave large bags or luggage. If you really have to bring a bag -- and it's preferable you don't, please make sure it's small. Only one small bag per person is permitted and it must not be bigger than A4 size. Under 14s accompanied by an adult 18+. A max of 6 tickets per person and per household applies. Tickets in excess of 6 will be cancelled. As part of the overall cost of your booking, O2 Guildhall Southampton have introduced a 2.25 per ticket restoration levy to help maintain and improve the facilities for customers, artists and promoters.
