I discovered today that my TA hadn't booked my cabin with the no upgrade option for our October 2023 Grand South America cruise.. We had cabin J 2619 booked. It's a large inside cabin with 210 square feet, midship near the stairs and one floor down from the promenade deck. We were given an "upgrade" to an H cabin. No specific cabin. These seem to be on the promenade deck where passengers walk past your window and are obstructed views. They are also only 184 square feet. I don't see how this would be an upgrade. We were not asked to make a change. I noticed when I looked on my Mariner account at my bookings to my surprise to see that my booked cabin had gone missing and only the H remained. I called and asked HAL to get my original cabin back and was told it's not possible. It's already been booked. I can be on a waitlist for my original cabin. I'm surprised that it's becoming so difficult to spend $25,000 on a cruise and get what you've paid for.
