Sarah,
I am doing this tour a week before you. I last visited NYC in 2006, and am so looking forward to revisiting there are great sights to see, I did do a posting about NYC.
I want to re Visit Central Park and take either a guided walk or a buggy ride, I want to see Ellis Island as last time I never got time for these things...if you put things to do in NYC in your search engine loads of great things should show up.
Have a look in the review section as there is a great review about this tour on there...
Cindy
