As a resident of the Baltimore area for the past 29 years, I think I can assure you that there are many opportunities to eat well and stay entertained at Baltimore's Inner Harbor. There are restaurants ranging from great burgers (J. Paul's) to great seafood (Phillips) to fair Irish (Tir Na Nog). There's a Cheescake Factory too! There are several fun museums and the national aquarium, as well as several warships to tour; and the Maryland Science Center is just around the corner. You'll have no problem filling a day.
To the O.P. How did you get the stay and sail rate for your hotel? I've tried several websites, and none of them seem to recognize the phrase. I live close enough to take a cab, but I'm hoping to find a hotel with a cruise stay-parking rate cheaper than the cab fare.
Recent victim of an on-board romance, and lovin' every minute of it!
