We were only dropped off by a cab. But seeing the place is also a convention center and a public buidling you can definately show up at the site early and walk around.. I do not know if you park your car for the length of the cruise on property if accessing that parking space is dependent on PAT. It's a great place to check out.. definately worth getting there early to walk about and take ship pictures. Theres a Starbucks right there too and bathrooms in the convention area.
