I have what may seem like a dumb question regarding cancellations....lets say I have a reservation starting Feb 15..and it says I may cancel until Feb 14. I understand I must cancel 1 day prior to reservation...can I cancel on Feb 14 by 3 pm or must I cancel Feb 13? I have received conflicting information from customer service. (Watching the weather and may need to cancel if weather does not cooperate.) Thanks.
