Build a "snowman" out of sand, wear swimsuits and Santa hats or write "Merry Christmas" near the surf while everyone gathers around.
Note: Our personal favorite is the image of the Futurama cartoon characters in Santa hats.
Nothing says "Merry Christmas" quite like a quartet of dogs clad in red Santa hats singing a moving rendition of "Ave Maria" as a gentle snow falls in the background.
Black and white paired with red Santa hats makes an easy to wear and polished option.
Reindeer antlers, Santa hats and jingle bell elf hats and shoes make fabulous choices for caroling.
