The disadvantage of blinds can be that they rattle in the wind, which can be especially annoying in a bedroom. This depends mostly on the type of guide rail, i.e., what kind of cable or rail the blind runs on. Also, many (all?) blinds rise automatically when the wind gets too strong. This means that you actually want them down, but that's not possible until the wind dies down. The advantage, of course, as you say, is that the light gets in when the blinds are down.
