We did the 30 minute tour which covered quite a bit in a short time. The boat is quick, so we were able to get from one location to the next in a short amount of time. Our captain (Eric?), was very friendly and accommodating. I also liked that this boat trip departed from downtown (near One World Trade center) rather than mid-town. My group all loved this tour and I would consider the 90 minute trip next time I'm in NYC.
