cherrin, welcome to FlyerTalk! One reason that we need more information to help answer your question is that there are often two key issues of hotel block bookings which arise: ones you wish to make with a hotel for a group which Efrem explained. Another which comes up is when an individual traveler finds that the desired hotel is sold out (or almost sold out) due to block bookings. So if you could give us more information of what aspect of block bookings you're interested in, and the property name/hotel chain, our members can be of more help. Ocn Vw 1K, Moderator.
