Marriott Niagara Falls Fallsview has for a number of years noted its cancellation policy as "you may cancel until [Thursday], three days before arrival." This meant in years past that you must cancel by Wednesday or get hit by the penalty. This year, when the same language again appeared, I called the hotel and asked what the language meant. The FDC replied that you had until Thursday to cancel. I asked what happened to the old policy. She said that while they still used the same language as before, they changed the interpretation because of many complaints. Same hotel, same wording, new interpretation.
