We have completed 30 cruises with Princess.  Our last cruise was in January on the Sapphire.  There was a change in our cabin that we did not like.  At night if one of us got up to use the restroom, floor lights next to the wall would turn on, probably to guide our way. We found it to be very annoying.  We use a flashlight for that.  Is there some way to disable this?  We will be on the Crown in Sept and are not looking forward to the bedtime lighting system.
