NY Port, not a pleasant question but I have to ask

We sail this Saturday from NY. Our first time from NY. We are driving up that morning (which I hope we make it in time)!!! Since I am a long time IBS sufferer I am very concerned about having access to a bathroom once we are at the port prior to checking in. Sometimes those lines can be real long. Anyone who suffers knows how quickly the panic can set in. Sorry for more details than you need to know but these boards are so helpful I thought I would give it a shot. Thanks!!

one in side(before you check in) there are large bathrooms immediately available.

No line in the ladies room at the port even when it was realy crowded on March 1st.

I have never waited on line for the bathroom in the cruise pier.
