So, I am trying to book two cabins across the hall from one another. One an interior and the 2nd an ocean view. So, 3 people (2 adults 1 child) in 1st interior cabin, starts out at 731 pp and then magically increases to 977 pp. Then choose 2nd cabin (1 adult and 1 child) goes from 831 they pick where cabin is or 1204, I pick. Why the almost 400 increase?
