Our cabin was #4000, the farthest forward on the port side. It has a window perhaps 5 square feet, deeply recessed in the wall. (You can actually crawl up in there to get a wide view.)
Other reviews have done a good job on the ship, but it's funny that the "no TP in the toilet" seems to get more mention than anything. We live in Mexico where you NEVER flush TP outside of some luxury hotels. (And nothing less than the Queen Mary 2 makes exactly the same request!)
Everyone compliments the ship's crew and we will too. Universally friendly and helpful!
