We were on the same cruise just a week later. I'd echo all of the above comments. I did turn the thermostat fan from "auto" to "on" which eliminated the cycling and provided a bit of white noise. The main dining room service was much faster than on the American Queen in 2019. Meals normally took about an hour as opposed to the Queen where they were often twice that long. Perhaps it had something to do with being short staffed because everyone really hustled and didn't spend much time chatting. The River Grill was open every night with no reservations required. While it was nice to sit outside and watch the scenery go by, the food just wasn't as hot nor as well presented as in the dining room. We elected to have breakfast and lunch there and dinner in the main dining room.
Only two minor complaints. We didn't notice much noise from our quiet neighbors but the plumbing was extremely noisy. Every time a toilet flushed somewhere the noise carried up through the shower drain. We also thought breakfast ended a bit too early. It's tough to sleep in get two showers in and get to breakfast when it ends at 8:30.
Any questions, I'll try my best.
