When we first booked our December 2023 cruise the Vibe showed as sold out. I tried online, online chat and calling and was told it was sold out each time. I kept checking back (via the app) every few days and one day a couple of weeks ago it was again available. I was able to book it for both my husband and myself. So, sold out does not always mean sold out. I don't know why it came back as available, but it did for the cruise we are on; so if I were you I would keep checking back. If it doesn't open back up for sale, I'd check as soon as I get on the ship. Good luck!
