I am surprised more rinks are not closing; most of the ones I visit seem pretty empty. Probably the council ones are subsidised, but goodness knows how the Planet Ice rinks survive.
I'm surprised to hear that. I'm in the US. In my area, we have the opposite problem. Rinks have been jammed. One private rink closed, but not due to lack of business. The building was leased; and when the lease terminated, the property owner decided they could make more money by tearing down the rink and building a warehouse. Skaters who used that rink, particularly the hockey teams, had to migrate to surrounding rinks.
Public sessions have been scaled back at several rinks I go to. But again, not due to lack of demand. The rinks have not been able to hire enough staff.
And over the summer, weekend public sessions usually are fairly empty. People tend to be travelling or heading off to the beach. But totally different story this past summer. Because of high gas prices and the overall mess with travel, looks like many people stayed home and decided to cool off at the rinks, instead of the beaches.
