I traveled with a group of 24, including a couple of families who are not U.S. citizens and whose first language is not English.
Everything that we needed to do was very clear. Our group moved through security without issue, the agents were pleasant and helpful. We had a few passports that would not scan, but that was handled when we picked up our sail and sign cards.
The port, including bathrooms was very clean. The lines (we arrived right at noon) were minimal - and, there were enough workers ensuring that people got into the right lines. It was s positive experience.
