This is not the first rodeo for the Vista. Back in 2019, I believe, they had serious issues with the propulsion system, and they limped back into Galveston like a day or 2 late. That was a long time ago, and just recalling from memory. I hope they get the issue resolved.
We were on her last August, and experienced no issues at all. A most enjoyable cruise. The Vista is a beautiful ship, with lots of amenities.
