I'm not driving to Florida from Maryland!
I did leave from the Port of Baltimore last cruise, but that port is limited in terms of where the ships that leave that port travel to. And that port needs to make it easier to get to.
Next time I would just take a shuttle from home to the port rather than Metro to Union Station, Amtrak to Penn Station, taxi to port. It was pretty heinous. And then when we returned, our ride from Metro to home decided not to pick us up and even told someone else who was going to pick us up that we'd made other arrangements (and we hadn't even asked her in the first place. She told someone else she'd take and pick us up and then didn't.). Needless to say, I have written her off permanently.
