It looks like there's only one booking date and they'll release tickets on 21/03/22 at 12.00 noon
I'm guessing they anticipate selling out -which they probably will do- but it does seem a bit weird to go on sale 9 months before Christmas Day and what , 7 months before they start up , if they have November dates .
I haven't been, I'd have loved to have gone , my DC are adults now so not their target customer .
