You can get around much quicker and more efficiently walking and taking the subway. We were stuck in traffic for hours. There is not a personal tour guide like I read on some reviews, it's a automated recording that mentions a few things here and there and plays music the rest of the time. That said, perhaps we were just stuck in traffic for so long there wasn't much to see. We had to take the detour the first day and couldn't even go where we were supposed to and the second day was a bit better, but we decided to jump off and take the subway to where we wanted to go.
Buses are old. They are not well signed around the Times Square Area. More evident around midtown 42nd street. Best go with another bus company as they seem to be everywhere. Also, the free Liberty Cruise ran out of fuel just as we were on the return approach to the Statue . We had to turn back, no refund, no photos, Nothing. Very poor.
