Cruising altitude isn’t always 35,000 feet; sometimes it’s at sea level on a passenger ship. Book a cruise on the Cape May Light, American Classic Voyages’ newest ship. Sailing nine romantic routes along the Eastern seaboard, the 226-passenger ocean liner makes port in such cities as Montreal, New York, and Newport, Rhode Island. But some vacationers may prefer to stay at sea, where they can enjoy gourmet cuisine and luxury cabins with views of the coast. Weeklong cruises start at $2,185 per person. (800) 846-8000,
