We just got off the Magic and we were in 7548. I prefer starboard because you usually get better views at the ports but that is not always the case. I think the views on this cruise were pretty equal on both sides (Scandinavia & Fjords).
That being said, we had room 7000 on the Magic last year, which is the equivalent to 7500 on the port side and we really liked that room. Very quiet because it was at the end of the hallway. There is a door leading to the officers' quarters next to the room but that was pretty much it. Would definitely book that room again (on either side of the ship). We like being forward because we spend more time in the adult areas and in the Walt Disney Theater than we do at the restaurants. But if there is a complaint, it would be the distance to walk to get to the restaurants and Cabanas. Did not bother me at all though. We love that location.
