My 7 yr old grandson and I had this room in Sept 2003. Really enjoyed the extra space.
Noise is a very personal thing. Some noise will really bother some people, the same noise will not bother others.
I did hear some running during the day. Someone feel down on deck and there was a thud. Of course I heard it, but it didn't bother me and was not really that loud. Sort of like having a room over you in a hotel. I didn't hear anything at night, and slept very well. Never anything very early in the morning, as some others have reported hearing from deck 8. I really enjoyed having the easy access to deck 9. Very quick, just run up the stairs! I would stay in this room again.
