My wife and I will be making a trip to New York City for our 1 year wedding anniversary in October. We don't have any family or close friends there, so we'll likely be on our own. We are going to be there for 5 days. I haven't been there since I was 12 and she has never been, so we'll be very touristy. I'm looking for recommendations about must do/must see things, including shopping to keep it MC approved. Interested in restaurants, buildings, cool photo op places, best shows to see, etc. Also, do you recommend renting a car or should we cab/subway it the whole time? Also, what would be a good one day trip to take (i.e. leave early in the AM and come back in the evening)? Niagara Falls seems like it's too far for that (800 miles round trip). Any other ideas? Thanks guys!
