We chose the express liberty cruise because we were short on time and it went by all the places we wanted to see. It's an hour-long cruise. We took the 11:30 cruise on a Thursday and it was only 1/4 full, which was nice. The restrooms (yes, not a boat "head") were clean with multiple stalls. They provide a couple snack bars. The tour guide was entertaining and informative. We saw a couple other tour boats while we were out on the water and they were so full, with everyone on the top level, they looked like they would topple right over. I was really glad we were on the boat we were on. Highly recommend this Circle Line cruise.
