Agree, doesn't look good for these two. Very sad, I always loved Nieuw Amsterdam/Noordam of 1983/84 with their functional lines, but their time has come and at 36 years, Marella Celebration (ex-Noordam) has had a good run.
Also, the writing was on the wall for Marella Dream. She was initially included in the 2021 programme for Marella that they issued when they withdrew Marella Celebration, but I guess they thought again, which is not surprising in the current market.
