You have to ask, is anyone seriously going to commit to summer 2022 when nobody knows what their employment situation is likely to be, even more so than normal, not does anyone really know where we will be in relation to covid-19, not the mention the fallout from Brexit. I know that for some people a holiday is an extremely important part of their lives, but seriously, committing to spend nearly 2 years down the line you have got to be either an eternal optimist, of just plain foolhardy.
From the company perspective I would imagine they are very much relying on plenty of optimists or fools to boost cashflow since there will have been precious little of the positive variety from the summer just gone.
