The '70s Rock & Romance Cruise is set to sail the mellow seas with a 2018 lineup that's scheduled to include appearances from Styx, Michael McDonald and more of the era's most successful artists.

Booked to embark from Ft. Lauderdale on March 3 for a five-day journey through the Caribbean, the cruise's 2018 edition follows this year's inaugural voyage, and boasts a roster that also includes America, Air Supply, War, the Guess Who, B.J. Thomas, Atlanta Rhythm Section, Badfinger featuring Joey Molland and Poco.

"I am truly excited to bring Styx music to the '70s Rock & Romance fans," guitarist James “JY” Young enthused in a press release. "We are planning on having a heckuva good time and everyone coming should plan on the same."

"It’s very unique for us," added America's Dewey Bunnell. "We tour a lot, play lots of venues around the world but a cruise ship is a singularly unique experience. We get to be here with our fans, see you on the various decks. It’s great."

Cabins on the 2018 '70s Rock & Romance Cruise are available now, with interior stateroom accommodations — which already have a wait list — starting at $1,349. The cruise's most expensive option, the penthouse suite with veranda — also currently waitlisted — goes for $6,699. On-board activities include Q&A sessions with the artists, panel discussions, game shows, culinary events and organizers promise "many many more" artists to be "added soon," all adding up to "the soft-rock voyage of a lifetime."

"The first ‘70s Rock & Romance Cruise exceeded all of our expectations in so many ways," said executive VP Alan Rubens. "It was fantastic to see how many people decided to spend five days with us, how unbelievable each and every performance was, and how great it was to cruise the Caribbean sharing and remembering the music we all fell in love to in that phenomenal era. We set the bar high and now are working to make the 2018 cruise even more magical and memorable."
