We bought tickets online, 5 days ahead of the day we wanted to go. That way we didn't have to waste time going in the morning of our 1 day stay, to get tickets. Reserved for a 6pm time. Did this so, that after walking all day we would have a relaxing drive later in the day. Glad we did. It was a very hot day & we really enjoyed this. Nice cool breeze when driving thru the city & fun riding in the river. Driver/guide was knowledgeable & fun. Glad we did it. We took the one that started at the Prudential Center. They take a picture of you & family or friends, with the duck in the backgroung. & the email you an eltronic version of it. But they also try to sell you copies of it at the end of the tour. & then they send you a couple more emails trying to get you to go the website & buy the pictures there. But we do have the digital picture in the email.
