I'm shocked that people would consider the characters re-appearing as negative. Personally i'd view it as something like Legend of Zelda. We get new link, new zelda, (impa, beetle, tingle, countless others) so when we see familiar faces we have an idea of who they are! (And make betrayal hurt all the worse, like beetle dropping you out of the sky shop if you dont buy anything.)
Both sides of it are interesting, them still basically same person but new environment expands on their character. Or them be different a defying expectations makes those reveals more memorable.
Like imagine if a certain red-head is technologically illiterate. Would be unexpected and suddenly, huh, yeah running a resort with no tech, no phones, all physical records keeping? No wonder there is trouble.
