I truly feel the term "noisy" leaves lots of room for interpretation. Some folks are bothered by even the slightest noise, and some folks can sleep through just about anything (like my DH!). I am sure the constant beat of the bass from a night club can be annoying, so try to avoid the cabins located directly below the night clubs (unless of course, you will be among those guests in those clubs until closing!).
Most other noises can be "drowned out" with some "white noise" such as a small fan running or a sound machine.
Then of course, there is nothing you can do about noisy neighbors or rude folks running the halls. If it get too bad, just place a call to Guest Services.
