What do you mean by open booking?

Open reservation means that hotels or other tourist accommodation places will open room reservations in a certain period of time in the future. According to the relevant public information, under normal circumstances, the hotel will release the news of open reservation in advance and provide reservation service, so that tourists can book vacant rooms in advance to ensure that they can arrange accommodation after arriving in the local area. This method usually allows tourists to book more competitive prices and better room types, and can also help hotels understand the room needs in advance and make arrangements for personnel and resources.
