After booking four cruises elsewhere because I'd lost patience with X's management moves, they finally instituted a cruise-only option for zeniths, so I upgraded an Eclipse cruise (A2 to S1) for next year which I was going to let go. The new invoice came through from my TA and instead of the usual suite $200 OBC for a repo cruise, it's only $125. She asked about it: "I questioned the onboard credit for booking onboard and he said 'this is for a single rate'." I'm still trying to determine how to compute a single rate for OBC. Oh, and they didn't honor the military discount with the zenith discount. Don't know if that's because I'm solo, zenith, or it was just simply arbitrary. I'm very cranky about this on principal. Haven't decided if I'll switch back to A2 or cancel. Grumble, grumble, grumble.
BTW, my Eclipse (2010 build) S1 Z-discounted price w/gratuities is $380 more than an identical cruise I've booked on Silversea (2024 build). I'd like to do both, but for sure, not in the S1 now.
