Hi Deb
it really depends how much time you want to be spending in your cabin

if you want to be there day and night, yes sometimes you might here them running by. but i would say maybe 1 out of 10 times.
i can only assume that you would be up and about early enough. besides there are signs that will tell your fellow passengers not to run during certain times of the day.
it of course also depends on which ship. the Star, Dawn and Jewel have the jogging track on deck 13 and there are no cabins underneath.
if you think it will disturb you, just ask your rep. to change it for you.
hope taht helps
