The tickets aren't really an issue. Most (if not all) of that will get refunded. If given the option of just rolling the booking over to next season, I'll take it (such good seats). In practice, that's probably more hassle than just refunding everyone.
A lot of us are going to lose money on hotel bookings. It's offset, maybe, by not having to pay travel, parking, food, merchandise, etc, but I suspect the financial hit comes on the POFW accommodation.
It's just a thing. Might even be some positive media exposure for the league in all of this.
Seen a few suggestions that a couple of EIHL clubs will REALLY miss the funds from losing the last few weeks of the season, so that's a worry too.
Be interesting to see how this all pans out and what people come up with to turn it into a positive.
