The Puget Sound is filled with lights throughout the holiday season, but no vessel can compete with Argosy Cruises' Christmas Ship, which docks in 65 waterfront communities to serenade people onshore and onboard with its resident choir. Those who choose to board the ship will enjoy photos with Santa, a reading of "'Twas the Night Before Christmas," and kids' activities. For a less family-oriented option, you can trail behind in a 21+ boat with rotating themes each week. It's also free to watch from the shore.
