Country is heading for the worst recession in all our life times. And to add further fuel to the fire we have the prospect of a no deal Brexit too that could still happen as well.
A lot of UK parks will be gone after this. A lot of other businesses will too. People need to wise up. The next 5 years maybe more are going to be tough.
I'm not sure whether Britain is comparable, but the German economy is predicted to be returning to 5.8% growth for 2021, with a 4.7% contraction for 2020 and a 10% contraction for Q2 of 2020. In the medium term, their economy should have returned to the level it would have reached had coronavirus not happened. If Britain is comparable, then the worst of the economic damage should have been done by the end of this year, and by 2025 or so, we should have returned to former economic levels.
With regards to Brexit, there seems to now be a push from many people for the PM to extend the transition period due to the exceptional circumstances that have occurred recently, so if enough people push for this to happen, I could see this being extended to 2021 or 2022 so that trade talks can happen, thus softening the economic blow.
Whatever happens, though; I think there will still be plenty of people out there visiting parks and other tourist attractions. There are many parks and other businesses that have survived far worse recessions than this one is predicted to be; places like Blackpool Pleasure Beach and Cedar Point have survived both world wars along with the Great Depression in the 1920s & 1930s, which was a far deeper recession than this one is predicted to be, as far as I'm aware. If you look at the amount of businesses that have been around since the 1800s or early 1900s (or even earlier in some cases), then I think that many businesses should be able to ride out the storm, especially with all the financial packages from the government; nothing of this sort existed during the depression or the wars.
Of course, I'm not saying that everything will survive this. Places will close, and jobs will be lost. But provided the business was financially strong pre-coronavirus, then I think it should be able to ride out the storm.
