Car Services
Manhattan offers a number of car and limousine services.  These services generally require advance reservations (which can be made online), allow credit card payment, and offer rates that can be comparable to taxi fares.  Two reliable services that we have used, both of which serve all airports, are:

Dial 7 (a reliable and inexpensive service; they do require you to call them when you arrive at the airport and will meet you outside the terminal).

Elite Limousine (also reliable, they offer some higher-end options such as meeting you inside the terminal).

Trains from the Airport to the Conference Hotels
From Newark Airport (EWR):
- Take the "AirTrain" at the airport to the airport train station. The ride lasts just a few minutes.
- Purchase a ticket on New Jersey Transit to New York Penn Station (there also, confusingly, is a Penn Station in New Jersey, which is not your destination).  The one-way fare is $15.  Trains generally run every 20 minutes or so most times of day, schedules are available at http://www.njtransit.com/sf/sf_servlet.srv?hdnPageAction=TrainSchedulesTo .   The trip to New York Penn Station takes 25-30 minutes.
- From Penn Station, you'll need to purchase a subway "MetroCard" with at least $2 on it and take the "1" train to 79th St.
- To the Belleclaire from 79th St.: walk two blocks south on 79th St. to 77th St., take a right turn onto 77th St., and the Belleclaire will soon be on your left at 250 W. 77th St.
- To the Park 79 from 79th St.: walk east on 79th St. past Amsterdam Avenue, you'll see the Park 79 on your left at 117 W. 79th St., approximately 1 and 1/2 blocks from the subway.

.From Kennedy Airport (JFK):
- Take the "AirTrain" at the airport to Jamaica Station.  You'll need to buy a MetroCard either at the airport or at your destination, with at least $5 on it (this card is also used on the subways, so you may want to buy a card with more money on it).
- From Jamaica Station, purchase a ticket and take the Long Island Rail Road to Penn Station. Trains run roughly every 20 minutes or so, depending on day and time.  The one-way fare is either $10 or $12 depending on time of day. Schedules are available at http://lirr42.mta.info/index.asp .  Alternately, you can take the E subway train to Penn Station for a $2 fare.  But this takes a long time (one our or so) and isn't the most pleasant or safe route, particularly at night.
- From Penn Station, you'll need to use your subway "MetroCard" and take the "1" train to 79th St.
- To the Belleclaire from 79th St.: walk two blocks south on 79th St. to 77th St., take a right turn onto 77th St., and the Belleclaire will soon be on your left at 250 W. 77th St.
- To the Park 79 from 79th St.: walk east on 79th St. past Amsterdam Avenue, you'll see the Park 79 on your left at 117 W. 79th St., approximately 1 and 1/2 blocks from the subway.
