we had a 9th floor studio room number ended in 18 and it was beyond fantastic! I'm sure floors 3-5 or 6 would be dissapointing, but I really think 7 and up are great.
Also, the photos don't do the view justice. Photos that are not zoomed tend to make everything look much farther away than it really is. We could see the entire MK from our room and loved every minute of it.
