I second that, we went on the alaskan cruise in oct 2010, seattle - alaska - vancouver, it was the last alaskan cruise for the year.
I was on the baxter cycler at the time, but decided to do just manual exchanges on board the ship. The bags were not initially delivered to the room, but after 1-2 hours it was delivered. Reason why I didn't want to bring the cycler along was I didn't feel like lugging it on board the ship (I didn't feel comfortable having the ship's crew deliver it).
But it is definitely good to know that the cycler works well on board the ship
