The New Kids on the Block are setting sail on the high seas once again, and tickets to their latest ocean voyage go on sale this week. The 2017 NKOTB Cruise to Cozumel, Mexico — featuring Donnie Wahlberg, Jordan Knight, Joey McIntyre, Jonathan Knight, and Danny Wood aboard the Carnival Triumph — will depart from New Orleans Oct. 19 and return Oct. 23, and you can join them, if you’re willing to pay your way (prices range from $699 to $3,449). Members of Block Nation fan club will have access to presale tickets beginning at 10 a.m. Thursday, and guests of previous NKOTB cruises can get theirs early, too, starting at noon. Tickets go on sale to the rest of us (a.k.a. the general public) on Friday at noon. For more information, visit www.NKOTBcruise.com.
