Has anyone done Circle Line 42 3-hr. cruise? We'll be traveling in & will do this. Office isn't open until later this AM - have couple of ?'s If I purchase advance tix online through their site....what age is senior citizens & if we book the 12:30 cruise on Sat. is there more than 1 boat going i.e., do they run several @ the specific time? Do we just show up @ will call? and assume we will get on as we have pre-purchased? or can we just wait until Sat. & buy tix there? concerned as it is Memorial Day weekend. thanks
