For the most part, this seems like the usual "cast of characters" although this may be the first time Disney has brought a ship to Portland. Overall, it seems like we have more - but smaller - ships calling as compared to pre-covid times. Some of these ships aren't much bigger than an average ferry.
"Zaandam" and "Mein Schiff" are regulars on the New England & Maritimes circuit and (as the names might suggest) cater almost exclusively to Dutch and German visitors on package holiday tours.
As an aside..."Zaandam" was the first cruise ship to experience a major outbreak of Covid during all the confusion and chaos of March 2020... It ended up stranded on the Pacific side of the Panama Canal and denied transit through the Canal while hundreds of passengers were sick
Another aside.... I've noticed that for some reason it seems like the German tourists ~LOVE~ Renys on Congress St...Go there on a day that one of those ships is in town and you won't hear a word of English spoken in that store.
