12. Titanic Mardan Palace in Turkey

Don’t let the name fool you – this place is very much afloat in luxury. With three wings housing 546 rooms, a five-acre pool complex, and a price tag of $1.4 billion to build, everything here is done on a grand scale. What sets it apart is its family-friendly approach to luxury – while parents enjoy the world-class spa and golf course, kids have their own paradise with a splash park and playground.
