Mgmt. was probably correct in not notifying guests of who the other guests were. It might have brought discrimination lawsuits against the Hotel.

OTOH, the manager should have had staff refer all inquiries to him and he should have explained the situation and offered a discount or refund on the spot. Don't wuss out and leave the high school clerk to act stupid and catch the heat from irate customers.

But should the customers have had advance warning of who the guests were? No.
