Just wanted to say if you are bringing alot of luggage, then use the curbside check in. The skycaps don't weigh the luggage. Helps if you don't weigh it at home before you go on the trip. Ours came out with just red heavy tags on them. Unlike delta who weighs everything and american who made us move stuff around to get the exact limit. Islip is a small airport and if you are not there early for your flight, seating is scarce. Don't know if you have little ones but it can be a bummer with also waiting for the southwest cattle call. I agree with the other poster, let one park while the other unloads. They have a little shuttle(like a mini school bus type) that takes you to the terminal. If you dont have too much gear, then I guess you can all get on the shuttle. You might ask someone, I am not too sure about this. We always take a car service there. We want to leave our car in the driveway so it looks like someone is home. But make sure you can loop right back into the airport. I am sorry but some people at the airport are not very helpful or friendly at all. I guess its all the security compliance stuff.
