Imagine being able to walk onto a floating luxury hotel, from shore to your suite's door, without having to pull out your passport or swipe a key card. Controlling everything -- from your room's lighting to a reservation at a restaurant or club or booking a tour of the next destination you're sailing to -- from your phone. And all of this on a ship designed from sea level up using the most modern construction techniques both within and without. When the Celebrity Edge launches at the end of next year, it'll be the most advanced cruise liner on the seven seas.
