It has not run either time we were there last year. I have a knee with issues (injury 4 years ago, but still "tight") and I have walked the pier both times. Also, when we've been there, there have been several ships and only ONE shuttle that holds maybe 15 people, (20 at most) and it only runs on the main pier. We've been down the side pier both times so you have to walk that distance just to get to the shuttle, if it's running.
