Jlmoran, I agree the complaints on the IV are prevalent, and also agree that it does not look that bad to me. (But haven’t sailed Edge yet, so no first hand knowledge)
the other big complaint I read is the reallocation of their sky view space to the suites retreat spaces. Coming from Royal I am familiar with such concerns, as royal on oasis class has converted the former Viking crown public space to suite only spaces. I understand they are unhappy, and they still have many other ships that offer public front viewing spaces. Just not Edge class.
i think the cruise lines are finding it lucrative to provide some special perks to suites, it does draw a lot of interest. We are a case in point...love these perks and enjoy them very much.
