It can't go to plan as bookings can't gain any momentum until a realistic idea of when UK-US travel will become normalised, and I don't mean the whole family of mum, dad and several kids masked up in a tube for nine long hours whilst paying hundred of pounds each and queueing for 4-5 hours to get in or worse, back in!
I called Summer 2020 a write off early last year, Summer 2021 will be equally non existent in these markets. It's nearly May and people haven't begun booking. If we're open again by 21 Jun in the UK, there will rightly be pressure to get our own house in order before open again to the world.
