Yes that is an oddity of the Celebrity booking system. It doesn’t seem to be able to handle the fact that the E class ships operate differently than the M and S class ships.
This is one of the questions that was asked of the CEO and her recent question and answer session and she chose not to answer it.
Celebrity does not begin to announce their new itineraries until November in December here. No one can tell you what they will offer in Norway until those are released.
On M and S class ships the elevators ding once if going up and twice if going down
in the restroom there are separate bins for the cloth towels, and all other trash, so don’t put the cloth towels in the wrong bin.
