Good question. I knew this would be an issue. Not what we were told at all.
If I were traveling next month, I’d call my TA/CVP and see if they could help. Probably not, but at least they could report it.
Try again after June 17th, if your cruise is after this date. If unable, then for a SD, book it once OB, call the dine line from your cabin phone.
Hopefully, you’ve already made your MDR reservations. Those were supposed to remain intact, if it was for a cruise prior to Sep 14, 2024.
