Due to covid ships have been sailing at less than 50% capacity to allow for social distancing.  We were ok with this but on the first cruises the passenger load was down around 600 passengers on a ship with a capacity of  2,886.    It was like a private yacht.

Celebrity has a move up program that allow passengers to bid on upgrading to a more expensive cabin.    We were very luck and were upgraded from a SkySuite to a Royal on the first cruise and to the Penthouse on the second.
