You might try calling them to seem if they can give you a better idea when would be a good time to arrive. Sometimes getting there extra early or extra late will give you a better chance at finding something. Last time I returned from WDW was late 9pm and there were alot of people driving out of the lots. Unfortunately HPN is in the middle of a residential area so it's not like there's a whole lot of other options (like arriving early and staying in a hotel or something).

But I must say the benefits for me have outweighed the hassles. I'm so much less stressed now about flying than I used to be. I've also never had a delay (knock on wood). In fact when I flew Jetblue they boarded early b/c everyone was checked in. We arrived in MCO about 30-40 min before our arrival time. Talk about a great start to my WDW trip!
