A 19 month old and a newborn

Should they share a room?! I don't want 2 crying babies at night! I will breastfeed and the baby will be in the bassinet in our room for the first couple months. Has anyone put 2 babies in a room? We have 3 bedrooms. The third has a guest bed right now and that's all it fits :/ I would feel bad taking that out so the baby can have a room, but then whoever stays over to help has no bed. Not sure what to do.
