I spent a night at the TWA Hotel recently. I wanted it to love it, but did not. There are cool aspects to it (I did not have time to have a drink at the bar). Access is a pain: you have to take AirTrain to Terminal 5, walk to the Terminal, then find the elevator to the hotel from inside the terminal. I tried walking across the street from the AirTrain station instead of going through the terminal, but I do not recommend it.
