Parking at the pier is expensive but super easy and very convenient. The ramp to parking is right off 12th Ave between 54th & 55th. You drive up, pay, then drive down farther to pier 88. Their will be security there with a dog. We have parked there 5 times and its always the same. You pull it, pop your trunk or hatch, and security and the dog walk around your car. As soon as you are clear you can pull over to the right and take your bags out.... leave one person with them (do this quickly) as not to create a backup. You'll be right next to the elevator to take you down. Go park, come back to the elevator go down, then outside to the porters. Drop your checked bags off, come back in the building and get in line for security and check in.
The above it pre covid, IDK if anything has changed
