There's a shuttle at the airport that charges $7.50, it drops you off really close to the hotel.
Unfortunately there isn't a shuttle, but the subway is less than a block away, very convenient, you should be in the airport in less than 40 minutes, and there's always Uber and lyft.
I stayed at the Sheraton across the street a few years ago and took a private shuttle. It may actually be less expensive to take an Uber or Lyft especially if you're more than one person.
