I left my car at Amerisuites (17th ave) for 20 nights while cruising. Not a problem at all. Would do it again. However, if you don't need the hotel the night before, I found an off port parking facility that charged only $5 per day. Don't remember name but you can find it through www.longtermparking.com.
