For those of you who bring a curtain to hang in the room for privacy, what kind of curtain do you bring? I keep going back and forth between shower curtain (obviously not the clear liner type) and window curtain. If window curtain, what length? My toddler will be in a pack n play and I’m planing on hanging a curtain around that. First time cruising with a kiddo so this type of cruise item is new to me.
