someone posted a while back complaining about noise in the cat 3 that's right next to your room...
but she said it was only noisy on one night and only until about midnight...if it were me, i wouldn't be in bed anyway at that time...
on the positive side, that room is midship which is nice....and very close to the elevator, which is also nice....
if you're really concerned maybe try calling them and asking for 8028....which is on the other side of the walt disney suite and possibly quieter...
but as i said, the woman who posted said it was only noisy on one night until midnight...but another woman who responded said she hadn't been bothered by any noise....
