There are fewer hotel rooms for getting married.

If the booking time is short, it can be temporarily remedied. See if there are any vacancies in the hotel. You can ask the hotel to adjust it for you. If you got married before, the hotel booked a room, and the guests haven't checked in yet, you can borrow it for temporary use. If the guest has checked in after marriage, you can tell the person in charge in advance and transfer it directly to you as soon as the guest checks out. In the worst case, if the relationship is good, guests can be arranged in a room. When you are most helpless, you can arrange the guests to a nearby hotel and find another person in charge.
