I thought I might never experience a cruise.... Until I found this one, which had no single supplement (that is, no additional $$ for having only one person in the stateroom). That, and the fact that I could drive to Charleston in less than 4-hours from my home in NC. (For an overview of the cruise, here's a link to my video: http://vimeo.com/84613460.

Hotel/Park & Cruise:
Embarkation was on Sun, 1/5/14, at 5pm, I drove down the day before, so as not to be hurried the next day. I picked the Quality Inn at Patriot's Point because of the decent rate and, especially, because they had the Charleston Cruise & Fly program. This is the only way to go: included in the hotel 1-night rate is parking for the car for the week, _plus_ transportation to the cruise terminal and back. Since parking one's car at the port costs $17/day (i.e., $85 for the 5-days), the net cost of the hotel is minimal. I went into Charleston Sat night for dinner, and can highly recommend Hyman's Seafood on Meeting Street. Fresh and fabulous oysters, scallops and crab cake.
See full review. Cabin was configured with king-size bed. Size, of both bedroom and bathroom, were fine for 1 person, and, I'm sure, absolutely ok for 2.
