In New York the best value sightseeing tour is that relaxing Circle Line boat trip around Manhattan Island. For just $34 those aboard get to see it all with great commentary. Remember: sit on the left (or port for more seasoned voyagers) side of the boat!

I've done it twice with visitors from Dublin. Let me say, I will only do it a third time under imminent threat of howitzer fire. "On your left, you'll see the world famous Woolworth Building, when built is was the tallest building in the world, it's now the 13th tallest building in the world and the 453rd..." is not my idea of "great commentary."
Is this your business?
