Flight
NYC has a ton of airports. Laguardia is the easiest to get here if you are not renting a car. Fly into Laguardia, take the bus to Harlem train station, and take the Hudson line to Peekskill or Garrison station. A taxi can get you to your final destination. Newark Airport is the easiest way to rent a car. JFK is the most challenging but doable (Kenneth and I have rented a car and drove up to West Point). Just be prepared to drive through NYC traffic.
Hotel
There is a room block here under Cline-Shields wedding! The ceremony and reception will be here! The Zulu lounge and in-house restaurants are places to get an easy meal. Let us know if we need to add more rooms to the room block!
Hotel
Walkable to the Thayer Hotel! The 5 Star offers large hotel rooms with fully functional kitchens. They are ideal for multiple guests or families. The Hotel is not located on post. You do not need a military ID to access the hotel, and it is available for non military individuals. There is a guard post located at the entry point to the hotel, but they just require a "REAL" ID or Enhanced DL to access. If you do not have a "REAL" ID, a Passport will be required.
Hotel
You would need a ride (rental car or taxi) but within a few miles!
Travel Note
There are many in the area! I feel like getting a group together and staying at one of these in the area could be a great option.
