We had two sets of flight pickup's from JFK and wanted a convenient place to act as home base since they were coming in several hours apart. During peak hours, the drive is a bit long. I think we spent a little over an hour in traffic the first time and about 15 mins in traffic the second time. I would definitely check WAZE for an approximation on traffic for the time frame you think you'll be making your trip/s to the airport.
The house itself was beautiful and there was plenty of space for everyone to sit around and chat.
