The Avalon field has a mess tent which someone described as ‘Proper basic good grub…Full English , Mac n cheese etc .Carbs and all you need for a good day out . Use your vouchers anytime . Can possibly get pack lunch for work shifts .
I think that is the only place you can use them.
5 days notice? That's pretty quickfire to try and offload that many tickets.
... unless I'm underestimating the demand and all the tickets disappear that quickly.
