Actually that floor plan is correct. What they call a dressing area is a hallway off the living area and the bedroom that you could certainly use as a dressing area since the bedroom is quite small. Also, even the 1 bedroom suite or B side has a washer dryer in it. Not so important if you're renting the whole 2 bedroom unit, but good to know if you are just renting the Suite as I have a number of times.
Also I have noticed that the lockoffs in several Wyndhams I've been in let a lot of noise through the connecting door. Sometimes a normal level conversation on one side can clearly be heard in the other. And if the other unit is playing a type of music you don't care for, too bad. Even when it's playing at a normal level.
