I have traveled in both the bedroom and roomette. For one person, the roomette is fine. For two people, I recommend the bedroom. On a recent trip to Florida from New York, my wife and I took the roomette. When the beds are down, there is hardly any room. To change clothes, it is nearly impossible. Do check your luggage as there is barely room for an overnight bag. The storage is very high over the center aisle of the train and difficult to move luggage in and out of the area.
Of course given the choice of a roomette or coach, yes, go for the roomette!!
