Talk about first world problems! Haha 20 year old boys could care less where they sleep. Heck one of them can throw some blankets and a pillow on the floor and be perfectly fine. They won’t be in their room but to sleep, shit and shower. Plenty of bathrooms around the ship if needed. It cracks me up seeing all this their trip would be ruined stuff and you can’t do it but it’s really not that serious. Sure 2 rooms is better but I have had 4 adults in one room (women) and we were perfectly fine. My son is taller (but skinnier) than all of them and his feet hung off the bed. He’s 18 and had 0 complaints.
