What makes a hotel count as truly luxurious varies from person to person. It could mean opulence in the traditional sense: gold ceilings, private pools, and chandeliers. Or it could mean personal service, like having your own butler, massage therapist, chauffeur, and someone to spritz you with Evian. To some, it's about culture: historic buildings, gorgeous architecture, and original priceless artwork. To others, it's defined by crazy panoramic views of the city and access to amazing natural wonders.
No matter how you define luxury, at least one of the hotels ahead is sure to shoot to the top of your must-stay list. Booking these may not be cheap, but the experience will be unforgettable.
