In October, there was NOTHING to indicate the Key boarding area, and likewise when we got on the ship. Lugged our carryon all over the place, took it to lunch and finally got into the room "a little early" when one of the doors was open. We had a room right next to the fire door so I did a quick in/out to drop out bag.
HOPEFULLY, they'll do a better job going forward. Didn't buy it for next month's cruise.
