I just received this in my email for next year's Solstice Christmas/NYE cruise:
However, when I click on the links it takes me to my Cruise Planner for that sailing but there are no dining packages offered (screenshot below). Also the last sentence in the above photo makes me laugh since you cannot select reservation times until you actually get on board.
I purchased this exact same trio package for our last cruise before the pandemic--it was also on Solstice during Christmas/NYE 2019. The price back then was $99.
