I’d say it’s likely to get worse. Lots of people with forward bookings likely kept them as they would lose their money otherwise. They likely won’t have that cohort of now-unwilling tourists next year.
This year the business devoted to tourism willl struggle. Next year the will start to go under. The year after that is when things get really ugly.
Likely some will go under this year. If enough go under, there’s enough tourists to support the others. The longer they last, the more the others struggle. Catch 22.
