This is completely wrong. I just called the reservation line and spoke with Janice. I wanted to know for sure because this may happen to us as well for our upcoming trip. She said locations that do not require a credit card hold do not charge under any condition. Guests are strongly encouraged to notify the location if plans change as soon as possible, but even if a member of the party arrives at the location at the time of the reservation and lets the host know they need to cancel altogether. I explained that I heard I would be charged if my wife and one of our daughters was unable to come with me and the other daughter to dinner--and she laughed and said of course not. I asked how this is handled at the restaurants that do require the credit card info and she said there is no policy in writing regarding smaller parties, but that as long as the party size wasn't significantly reduced it would not be an issue. OP, thanks for asking the question--I hadn't even considered possible consequences. Glad there are none. Still, I hope people are responsible enough to change or cancel their reservations so others have the opportunity.
