The Grammy-winning Zac Brown Band is hosting a floating festival on Labor Day weekend, and you’re invited! The musical cruise, dubbed Sailing Southern Ground, promises to be a weekend getaway you’ll never forget. The fun happens on a Carnival Inspiration cruise ship that departs from Tampa, Florida on Thursday, September 2, 2010, heads to the gorgeous Caribbean island of Grand Cayman, and returns to Tampa on Monday, September 6. Along the way, you’ll enjoy great food, great live music from the Zac Brown Band and other acts, and beautiful scenery.
