We stayed at Cosmopolitan for the second time this last trip. The first trip, we stayed in a terrace studio with a fountain view in the west tower. This trip, we tried to upgrade at the front desk to a terrace suite, but they wanted us to pay, so we stuck with the terrace one bedroom with a fountain view. Both rooms are great and are the same square footage. However, the devil is in the layout as they don't say. With the studio, the bathroom is the first thing you have as you enter. The living area then blends essentially seamlessly into the bedroom area (there's a half wall sort of separating them). With the one bedroom, you enter into the living area; you then come into a sort of dressing area with the closet and an ottoman facing the entrance to the bathroom, which parallels the bedroom, which can be separated from the living area with a pocket door. Obviously, one can see all of this on the floor plans on the website, but actually being in the rooms highlights some significant differences. The one-bedroom's living area is significantly darker than the studio's, being so far from the windows and because the bathroom being parallel to the bedroom creates a smaller opening for light to get back there. It's cool having the bathroom with a view, but it didn't really do all that much for me, especially since when one is in the bath, you're actually too low to see anything but sky. With the bathroom parallel to the bedroom, the space around the bed is pretty darned cramped. It doesn't show it anywhere I could find, but there are windows between the bedroom and bathroom (with blinds). Yes, it's potentially sexy or something, but it also lets in light for those late-night trips. As you can see on the floor plan for the one bedroom, there's a pretty significant waste of space in the area that constitutes the dressing area to the living area. It was nice to have the big ottoman and stuff, but I didn't need it. As you can probably tell, I think I liked the studio much better than the one bedroom. I can see the one bedroom's advantages -- one could be in another place and not disturb a sleeper; having a bathroom near the bedroom -- but the layout just didn't appeal to me. I liked lounging in the studio's living area and even working at the desk and looking outside at the great view. So, I just thought I'd share so you might be able to make a better judgment between the two kinds of rooms since they are often priced the same.
