Since when do Celebrity or RCI allow you to make show reservations before you cruise? Sailed on the Apex in January and the Oasis in June and neither allowed show reservations before hand.
If you come up with a more valid reason than Covid, then let me know. I could make show reservations on our 3 Escape cruises in 2016 and 2017 as well as the Bliss in 2019. Can't make them for the Prima this month or the Encore in January. It could be a temporary thing or a permanent one, but post Covid it's not allowed and pre Covid it was.
