New York in a few days
Stick to Manhattan if you just have a few days. Day One: go downtown to see the Freedom Tower, ferry to Statue of Liberty and Ellis Island and then hit Chelsea Market for dinner and shopping. Day Two: walk or run Central Park planning to be on the east side of the park at the end so you can visit all of "Museum Mile" (Metropolitan Art Museum, Guggenheim, etc.), then drop down to Times Square for dinner/shopping. Day Three: Walk Brooklyn Bridge and visit some old churches.
Insider Tip:Jimmy's Corner in Times Square actually has cheap drinks (no food) right in the middle of the action. It's a great retreat from blowing money on cocktails, but it's small so get there before the evening rush. Cathedral Church of St John the Divine is not-to-miss if you're into some religious history.
