I understand that there are some lower capacity cruises, primarily in Europe, but the jumbo monsters based in Miami and Fort Lauderdale have all the charm of Continental Trailways.
And don’t forget the cruise port of Galveston, Texas. It is huge.
Also we use Continental Trailways for trips between Bangor, Maine and Boston. It stops at the airport-so we don’t need to park our car in the Boston airport.
