We arrived at port about 11 am and waited for about 45 minutes for check-in to start. Once it started it was quick and we were in our cabin shortly after noon.
We were in an interior cabin. Previously we had booked balcony cabins, but decided to try an interior this time. We think we will be able to afford a lot more cruises if we book interiors. I was a bit leery of an interior when we booked it, but it turned out to be quite alright. It was small, but quite comfortable. We were hardly in it except to sleep or shower and change. It was located just aft of mid-ship and we found it to be a good location.
Our only complaint was that the a.c. was not cool enough even when set at the lowest temp. It was adequate, but we would have liked it a bit cooler. We heard the same from several other people. We also found the a.c. around the ship to be a bit uneven - some areas cool, others a bit on the warm side.
Cabin B520 is an interior on the port side just aft of mid-ship. It was not too far from the laundry room, but not close enough to hear any noise from it. I don't think there was any crew space near it. It was a quiet location. Only complaint was the a.c. was not quite cool enough. It was adequate but we would have liked it a bit cooler.
