This is something Celebrity dose and it works. I'm not sure why but it does. You are instructed to drop off your carry on(s) and leave. No lingering. Speaking only for ourselves, that's exactly what we do. Pick up our Seapass cards, drop off our carry on(s), stash a few things in the safe and color us gone. Head to a bar, have a drink or two and chill out. Then ~ 1:PM the general announcement is made that staterooms are open.
