We are planning to take in the Fall colors from a cruise ship departing New York in October 2016. Alaska flies to both EWR and JFK.

The plan is to fly in about 4 or 5 days before the cruise. We'll also spend the night at the end of the cruise before flying home.

Which airport is better?
Any suggestions as to must-see sights?
I haven't been to New York in probably 20 years! I'm sure a lot has changed.

Thanks.
