Definitely Skip This One!
We went on the three hour tour. What a horrible experience we had. The boat was old, the seats were uncomfortable, and the PA system was so bad that we couldn't understand the tour guide. People are packed on these boats so that contributed to our overall lousy experience. But there are other problems you should be prepared for if you pick to see NYC this way.
Once the boat starts looping around Manhattan, you'll quickly discover that for some sights, you picked the correct side of the boat to sit on but for other sights, you didn't....and you're pretty much stuck with no view. (Either you won't see the sight at all or you'll see very little of it.) You're not allowed to stand except in the very front of the boat and since all seats are taken, there's no running over to the other side with the view, either. Of course, the front area of the boat is open and allows for a perfect view of all sights but it has a very small capacity. Those who manage to quickly get to the front of the boat know they've got a great spot for seeing everything on both sides of the boat and looking up so they stay there for the entire boat ride. Everyone else is pretty much stuck with looking out just one side unless others leave their seats on the opposite side. Of course, if you switch, you might find you're now on the wrong side to see the next few sights. Grrr.......
The three hour boat ride was also WAY too long. We were bored after the first hour. The beginning of the ride is quite nice when you're near the Statue of Liberty and seeing the tall buildings of Manhattan but it's all down hill from there.The second hour has sights of mild interest; the third hour is absolute torture. It probably would have been slightly better if we could have heard and understood the tour guide at that point but that was impossible. Everyone was complaining and frustrated by this, too, but what can you do once they have your money and you're stuck on the boat? Additionally, not only are the boats old and run down, the food is expensive and lousy.
Skip this one. Instead, buy a ticket for the Gray Line sightseeing bus tour of NYC and get off at the stop for the Staten Island ferry if you want to see the Statue of Liberty & Ellis Island. We found the tour guides on their buses to be fun, informative, and completely intelligible! The buses stop at interesting places all over the city where you can either stay on the bus and listen to your tour guide some more as it continues to the next spot, or you can get off, take your time exploring that location on your own, and then walk back to the bus stop to catch the next bus whenever you're ready to see more. This is definitely the better way to see the sights and hear your guide. We had a blast!
