The 1 & 2 bedroom suites in the south tower are regular rooms with a parlor room in between. Very nice if you need the extra beds. I prefer the mini suites that are just one extra large room with double sinks, wet bar and a walk in closet. They have one mini suite on each floor of the south tower and they all end in the number 54. You also get a great view of the strip and zero noise from FSE. BTW, the 25th floor rooms are called penthouse rooms. They have three that are large and two that are the size of a regular room. When we were married at the Plaza, they gave us the largest one and it had a hot tub and a walk out patio. The main problem for the 25th floor is that only two of the six elevators go there and when you are waiting for one of them, people will hold their elevator doors open for you and when you tell them no thanks, they give you a funny look.
