First, we had a great time on the cruise.
What was awesome...
(1) Visiting these great ports. Most of these ports are awesome DIY ports where you can see and do and learn a lot without expensive transportation or tours; if I start into that I'll surely surface the word limit for these reviews.
The room was fine. I would not hesitate to choose this room again (other than the general issue of the ship overall with the smell of sewer gas). Overall I think this is a pretty smart livable layout - it was very comfortable and niggle-free. The bathroom sink faucet provides only a trickle of water (but I think that's also a ship-wide thing). Category M is a guess; I don't recall.
