Fans attending the Zac Brown Band's concert at Boston's Fenway Park on Sunday took home more than just memories. The band's frontman surprised more than 37,000 concertgoers with a free cruise trip for two aboard the Margaritaville at Sea. Zac Brown Band holds the record for the most consecutive sold out performances at the venue and the most tickets sold in its history. The Zac Brown Band said it is giving away four cruises per show. However, those fans will receive a cruise aboard the Beachcomber, a new ship debuting in January 2027 that includes a live music venue called "Same Boat" that was co-designed by Zac Brown.
