Walking in from where I'm staying a mile or so away, would be handy if backpacks are allowed so I can put meet and greet items/merch in there to keep them dry and make them easy to carry, etc.
(Context for the haters; its raining in London today 😛 )
EDIT: Asked a guy at the meet and greet and as long as it'll fit under a chair and they can search the bag on entrance, it's fine.
