On both of my Disney cruises I had an oceanview room. On the Disney Dream I had an oceanview guarantee and they assigned the room about 3 weeks before my cruise. We had a handicapped accessible room at the rear of the ship, it was probably 3-4 times the size of a regular room and somewhat triangular! This time, on the Magic, I had a Category 9A. I picked the room this time and it was perfectly mid-ship. We were two rooms away from the mid-ship stairs & elevators which was very convenient.
I was very happy with our room. The window was large and round. My son loved to look out and spot the waves, ports, and rain (yeah, we didn't have great weather!) The window seat wasn't a real seat, but it was large enough for my son, almost 3 years old, to hang out. Some people worry about Deck two being too low on the ship. I took an exterior photo from the dock in Cozumel to show how high the deck two rooms really are! In the bottom right photo you can see a few levels of the ship. Deck one is the small double-round windows. Deck two is where the larger single-round windows are. Hopefully this helps clarify how high/low the rooms really are!
Disney bath products, to the right, smell spa-like. You receive this set up upon checking in to your room. If you use them up, the room attendant will gladly bring more!
The split bath is a concept that I think other cruise lines should adopt. Carnival has some on their newer ships, but not in all categories, just a few oceanview rooms. The split bath is essentially two "bathrooms." The first one, closest to the door of the room has a sink and toilet. The second one has a sink and a tub/shower combo. The reason why it's a great concept is that someone can shower or bathe without restricting another person's access to the toilet or sink. The bathtub is great when you have young kids. If you have teenagers or girls, the dual sinks/mirrors are also a blessing!
