Cabanas, not cabins.
If you search around thebowrd, there are dozens of threads about cabanas. Many, including us like the aft facing cabanas as the moving air is important in warm climates. Others like the ocean view. We had one once (out of 7 cruises with cabanas) and have never booked one again.
Bar service in the cabanas is handled very well by the cabana attendants. Otherwise, the Crow's Nest bar is forward on the same deck. On N. Amsterdam, the nearest restroom is just outside the Crow's Nest.
