I was on the carnival ecstasy w/ my family of 4. we booked two rooms next 2 each other but my friend's family of 4 booked one room. there were 2 twin beds, a bunk that pulled down from the ceiling, and another twin bed was placed there. it was cramped though. not too much space to walk. their room might have been cheaper, but w/ 2 rooms u also get 2 bathrooms.
