Sure, New Kids might not be selling tons of records these days, but they have sold out some big venues recently, Drew said. Plus a band-themed cruise means big money for the group.
The premium for a trip like this is about $500 more than a regular cruise, Rose said.
"It is very profitable," Drew said. "And they cut into a share of the profit. They aren't just a regular cruise ship entertainer."
Rose said the added price is worth it for the fans.
"People are looking for more than a regular cruise experience. They are looking to get close and personal with the entertainer," he said. "We're offering entertainment that they can't normally get on a regular cruise and they're getting more than they could get from a regular concert."
The company has seen the market for such cruises grow. Last year, they had 7, this year 11.
On a typical cruise, Sixthman brings about 15 to 20 full-time employees, five production assistants, 15 to 25 production staff and sometimes a security crew of five to 20.
Vance Gulliksen, a spokesman for Carnival, said his company loves the cruises. First of all, the bands sell out ships. But second fans fall in love with cruising and come back for their own vacations.
Newerth is one of those people.
"I had never been on a cruise until I went on a New Kids cruise," she said. "Now, I'm hooked on it."
