Train
You may also take the local buses but the travel time is 3 times the usual travel time using the train. Also, maintenance repair are made on weekends so please allow extra time for delays or longer walks.
Flight
Hotel
Best bet is to find a hotel/flight deal as local hotel reservations are much higher. The church is on the Upper West Side of Manhattan, we recommend staying in this area or in Lincoln Square, Midtown, Times Square, or Hell's Kitchen but the church is fairly easy to access from anywhere in NYC.
Travel Note
Lyft, Uber, or NYC taxis are all fairly reasonable and reliable.
