I agree with noise level. There is no way to determine what that will be until you are there. We once stayed at Yacht Club and we loved everything except...... our neighbors were with another group up the hall so every morning, earlier than what we wanted to get up, Dad would come out with son and send him RUNNING up the hall to his friends and then YELL "WE'LL SEE YOU SOON!!!!!!" and then slam the door behind him. Twenty minutes later, the Dad and Mom would come out of the room, slam the door behind them, and YELL, "COMING UP NOW!!!!" because the family down the hall had their door open. Then the kid would come out of the room up the hall and YELL "OK DAD!!!!!!!!!" Then the entire group would go off for breakfast and come back an hour or an hour and a half later and repeat things. So - you can't choose your neighbors in a resort of any kind. And yes, after the second day, I did speak to the Dad and asked him to keep it quiet. Still the same routine but half as loud. We were not happy at all.
And with outside hallways, there are parents who feel the need to have their kids run up and down those outside hallways while the parents are getting ready for the day. I can't tell you how many times we've had kids running around and yelling and even stopping right outside our door for a "fight".
