5. You can order your drinks from a robot.

The Bionic Bar by Makr Shakr has two robot bartenders that can make a number of cocktails. Pick up an iPad and type in your request, then watch as the robot whips up your concoction.

The Verdict: It’s a fun novelty, but the crowds are — not surprisingly — large, and the waits for drinks can be long. Plus, there are so many comfortable lounges onboard that this small space pales in comparison. Still, you should wander by and watch a cocktail being shaken up at least once — on your way somewhere else.
