The cruise-ship theme for parties can incorporate exotic locales, ocean views and naval elements; bringing all these together will make the cruise-ship theme come alive. Make the night complete by incorporating games and activities into the cruise-ship theme and serve a seafood buffet or dinner.
Decorate the door and entryway. Take a picture of yourself, or the guest of honour, in the costume of ship's captain and blow it up. Place it at the entry or outside the door and add a word bubble with a joke or welcoming message. Hang a ship's wheel on your door with some blue and white streamers around it.
Decorate the walls in the main party area. Hang portholes with ocean views or pictures of exotic landscapes behind them. The blue and white streamers should continue into the party area. Hang some of them at waist level to mimic ocean waves and drape some near the ceiling with life preservers hanging in between. Add a large ocean stick-on mural on a wall to add to the cruise-ship feel.
Decorate your tables with blue and white tablecloths or with cloths that have a shuffleboard or wave pattern. Use cruise-ship towel animals or ships in bottles as centrepieces. At the end of the party, you can hold a "ship's lottery" and award them as prizes.
Decorate the bathroom. The bathroom is an area that a lot of people don't think about when it comes to decorating for a party. However, it's a good idea to put out hand towels, tissues and hand soaps when having a party and there's no reason not to bring the theme in there as well. Put out blue and white hand towels, tissues with a sea theme or soaps that are shaped like ships, ship's wheels or seashells.
For an activity that ties into your theme, make a guessing game out of the decorations by rewarding guests who can name the locales.
