Where your terms are written
Cancellation terms are set by the rate you book, not by the group as a whole. A flexible rate and an advance-purchase rate are different products with different prices, and they cancel differently — that difference is the reason one costs less than the other.
The terms that apply to you are shown before you pay and are restated on your booking confirmation. That confirmation is the authoritative record. If you cannot find it, reservations can send it again.
