I miss the old days when RCI would sometimes just surprise you with a complementary upgrade. That was how I got my first balcony. It is also how I got hooked on balconies.
If you can pull it up later the segment is 31 minutes into the show. It is funny how they use some stock cruise ship photos that are neither Serenade nor even RCI. They did show some people who are on the ship. I think they used snippets that they got off of social media.
