Is there parking?

We park @ the relatively small public lot, in close proximity to the Portland Discovery ticket both. Probably having a few available spaces left was due to cool rainy weather. But I recall it running about $20 bucks

Be prepared $50.00

Portland Discovery does not have it's only parking, but there is a lot of public parking close to them. It is expensive parking in Portland no matter where you park. Spaces along the streets are cheaper than in the parking lots, but the street parking has strictly enforced time limits (generally 2 hours).

Yep

Yes, down the street there is a paid lot
