After analyzing the costs with Plus and Premier packages and comparing to what we actually participate in when on a Princess cruise (we are elite), we have come to the conclusion that the extra money for the packages is better spent securing a Reserve Class Mini-suite. We do not drink alcohol to any extent, we do not go cruising to eat pizza (even though we love pizza), and we get the minibar setup exchanged for drinks we do like. We eat breakfast, lunch (on sea days), and dinner in the Reserve Class dining room. Plenty of seafood, pasta, meat dishes, custom menu items, great service, no lines, no reservations. We do not use room service or order food on our medallions.
Yes, I know, we sound boring. However, we have a blast on our cruises and even have four more booked. Cheers, y'all.
