There are many hotels located in the immediate vicinity of the cruise terminal. Radisson Admiral Semmes Hotel has a $99 cruise deal. Hotel room and complimentary parking - plus their shuttle will take you to the terminal and pick you up after the cruise. Also includes a contintental breakfast. I think it's a good deal. I happen to have their number: 215/432-8000.
Otherwise, the terminal parking garage fee is $10 per day.
I love the Holiday - have enjoyed cruising on her six times. I have a cruise booked on the Holiday for June.
