I would be happy if Marriott switched out every CY w/an Aloft...at least you would know exactly what you are getting consistency-wise, and it would be new. But I always seemed to have found the crappy CYs. Elements are great but are few and far between.
If more HHs were like the one in Evanston I went to a week ago (felt new build, very on trend) I would be happy...the crappy one in Addison TX a couple weeks ago I'm guessing was an Ameriprise.
