I just noticed this on the Princess site and wondered if other cruise lines do this:
Each time you book and sail in a full suite or sail alone in a stateroom in which you pay the exclusive occupancy fare we will count it as two cruises!
Princess only requires 15 cruises to be Elite (their highest status) and I reached that within a year (Two suites and two solo cruises must have counted as 8 cruises!!!) I was never sure why I had reached it so quickly. Princess also counts days and allows status credits for days or cruises (whichever is higher).
Do other lines do that???
