No, you were not imagining that! We all read the same thing but I believe that pricing strategy quickly died. I would imagine that many people book early to secure the room they want but once they heard the pricing would not get better than what was being offered, they may have stopped booking early.
Princess was forced to claw that statement back .. never formally, but in practice, that’s what I’ve seen.
I was annoyed a month or two back when I had an offer and they clawed it back. It wasn’t a system glitch, like described in this thread but I was just shown that it was offered, even got my bookings and they took off all the OBC showing on my invoices. I got it all put back on my bookings but it made me question my loyalty .. for just a short time, though. Princess checks all the boxes in what we expect out of cruising, so all has been pretty much forgiven.
