Is it necessary to book a block of rooms for wedding guests? The reason I ask is that I can't find an ideal hotel for guests. I'm getting married in San Francisco, where hotel rates are very expensive in summer, even if I were to book a block. Meanwhile, I have no idea when people will decide to arrive. I have a bunch of people coming just for the weekend, and then my FI's family and friends are international, so they will be staying for a week or more. Given people's varying price points and schedules, I'm thinking of just giving them a few suggestions and not booking a group of rooms. Would that be impolite?
