We did the TWA overnight once and if we were going to do a JFK trip again we’d consider TWA again. With that said, read the reviews to get an idea of what to expect because it is a bit of a unique hotel concept. Two key points are that service is a bare minimum (self check-in, no bellmen) and it is a long hike on soft carpet to get to your room. It was super convenient for an early morning departure with two kids. But on our return I was sure to borrow a luggage cart from the terminal because wheeling bags over that carpet certainly hit my cardio goal for the day.
