Closest train is about 20 minutes away in Beacon. It is approximately 1 1/2 hours from Manhattan to Beacon by Metro North Hudson Line and depending on which NY airport you use it is at least an hour to Penn Station. So just realized that it will be at least 3 hours from the airport to the hotel and most like going to be closer to 4 hours or more. Keep that in mind when deciding if you might want to fly to an airport with a connecting flight to Stewart.
Beacon train station across the Hudson river. Or the middle town station. Both are probably around the same distance. Beacon might be a bit closer. I like beacon though. It's easier to navigate, and goes directly to grand central.
