In general, I guess I'm not as generous as some of you -- I pay for service then I expect to get it. A business can close for a holiday, but if it chooses to remain open and charge regular prices, regular service should be provided.

That said, personally I wouldn't care. But customers should be notified beforehand, for example, notice included in the confirmation reservation email. And, obviously, with a sign/notice at the front desk.

It is unclear whether this is good news for employees. Housekeeping staff may well be hourly with only modest benefits -- i.e., they don't work, they don't get paid. Some will enjoy the time off (even without pay), but others may well prefer/need to work. Obviously we don't know those details.
