Adventurers Alex and Luke (www.alexandluke.com) concluded their seven-day Alaska cruise on the Carnival Spirit this week and discussed their trip on their weekly show “Monday Evening with Alex and Luke” on YouTube.

Check out the video during which they highlight their favorite sites and moments of the cruise, including Luke’s debut as the “king of the world” at the ship’s Club Cool Lounge singing karaoke to “My Heart Will Go On,” which was suggested by blog readers.
