we were on vista last may. We missed half a day in jamaica, totally missed grand cayman, and got full day in cozumel. We got a very small OBC for missing ports.
its scheduled for dry dock next year https://cruiseindustrynews.com/cruise-news/2022/12/carnival-vista-to-drydock-in-2024/
we hope to never book on it again, in my opinion, carnival knows its messed up and gimps it along to make money until they dry dock it, and if it breaks, too bad. They keep saying unexpected issues, but after years of it happening, how unexpected can it be?
edited to add the cruise before ours went off without a hitch but got in late so i'm pretty sure issue started when they left cozumel back to galveston. I hope anyone on it has a good cruise. Its just a bummer when you spend 5 out of 7 days at sea..
