I believe they do listen though.
Like it or not RC is the family liner and is also catering more and more to the young adult cruiser.
Im not young, but do have teens, and they are very much looking forward to the purple slide among other things...also not much use for the champagne bar for those with young families.
Not saying what you are saying is invalid, just that its clear their market is now focused on young adults and families...and that they are now cross promoting Celebrity more than eve in an attempt to lure older cruisers (or those that like the finer more sedate things) to their sister ships.
They can make far more from a cabin of four than a cabin with two....so they are doing their best to retain the family demographic over others like Norwegian, Disney and to a lesser extent Carnival
