Forget the 'Rough Guides', Lonely Planet is brilliant! I took this to NYC and found it invaluable. The maps are really easy to use and I love the little narratives at the front. I've gone back to this book loads of times since getting back, and have found new places that I wish I'd have gone to. I'm planning on going back in September, and this time we're going to Philadelphia (only a 2 hour bus trip from NYC), there's great information about excursions in the back of this book too if you're there for long enough. Enjoy NYC, just don't forget your comfy shoes!!!
