I completely agree. My favorite thing to do on a cruise ship is to walk around the promenade deck for miles. That is why I liked Holland America. Unfortunately, they have cut way back on their entertainment. That is why for my next cruise I will be returning to Princess.
My favorite promenade deck is on the QM2. Three and a half times around is a mile. It also has the classic ocean liner wedding cake design where there is public outside space on multiple decks at the stern. Crystal also has a design like that but its ships are much smaller
