We wished the Promenade deck went all around too - and having the exercise room where it is, with no windows, is less than optimal, I think. I skipped using it on this cruise, so we got our exercise by doing stairs rather than the elevator almost all the time, and walking on the Promenade deck. But if we don't cancel the 2024 World Cruise I'll probably want to use the exercise room some to help burn off all the calories consumed and to keep my muscles in at least halfway decent shape. The newest Princess ship we've sailed on was the Regal Princess in 2019, on a transatlantic/Baltic cruise. We liked that ship, especially Vines, the International Cafe and Alfredo's.
