What is the best bet for parking in White Plains if I do not have a permit?

The garage has metered spaces- you have to go all the way to the very top. The few times I've parked there, I've arrived around 6:30 and there have been lots of spaces, but it's hard for me to say how quickly that lot fills. As an alternative, you could park at the Galleria at a meter and walk the few blocks to the station. I have a feeling those spaces are open longer and it's a short walk. My husband used to reverse-commute and kept his car at the Galleria garage, so I imagine they open pretty early.
