I went last year and loved it in fact it was part my Christmas Gift to my sister in law as we went to New York for her 30th Birthday in January
It picks you up by Plaza Hotel and has quizzes re Sex and City
They take you to the shop where the Rabbitt is from
Then they take you to the Magnolia Bakery and you get a cup cake as part of the tour
Next up is Carrie's Step, where everybody gets the chance to get their picture taken

The only other place that you stop of is a bar called O'Neils that is the bar they used for Steve's bar
You then go round a few differnt locations such as Meat Packing District etc to see places where scenes were filmed in sex and the city and they have TV's on with the scenes from the programme where each place you are visitng is filmed.
it takes you back to the plaza. You are on your own special tour bus for the tour
I enjoyed it as did my sister in law but I think if perhaps you are not a fan of sex and the city you might get a little bored, that said, it is a nice way to see New York in the warm, as you can see when I went it was a little cold!!
The pick up and drop off point at the Plaza is also an ideal opportunity to pop into Tiffany on 5th Avenue as well
