SeaDream I is one half of the pair of identical small ships operated since 2001 by SeaDream Yacht Club. This 112-guest ship, which was built in 1984, a year before its sibling, SeaDream II, offers an upscale but decidedly casual ambiance best exemplified by the weekly Champagne and caviar party on the beach. SeaDream I sails primarily to lesser-known sun-kissed ports in the Caribbean and Mediterranean, but no matter where you are the service is exemplary. Plus, a multi-million-dollar refurbishment in 2022 updated the staterooms and other interior décor and added a new teak deck and two forward-facing Jacuzzis.
