For many of us, staying in any private hotel room feels like a luxurious experience. Just give us a bathrobe, freshly cleaned sheets, and a mint on our pillow, and we'll be happy.

But let us give you a tour of some of the world's most expensive hotel rooms, which can cost guests upwards of $45,000 per night (seriously). If you're willing to drop a year's salary on a single night in a luxury suite, you'll get a taste of the decadent life of the ultra rich. For $41,000 per night, you can relax in your hotel bed beside paintings by Picasso and Matisse at the penthouse suite at the Grand Hyatt Cannes Hotel Martinez in Cannes. For $45,000 per night in the presidential suite of India's Raj Palace, you can live like a king or queen in a room filled with ivory furniture and gold-leaf-painted walls. And we thought we were living it up when we take a drink from the mini bar and buy a movie on pay-per-view. If you want to live a night like a billionaire in one of these hotel rooms, you better start saving your travel points now . . . or get really good at sweet-talking the front desk into a room upgrade.

If you happen to be a billionaire reading this looking for a place to crash for the night, we've compiled a list of the world's most luxurious and pricey hotel rooms. If you are not a billionaire but want to see some of the most over-the-top hotels on the planet, check out the photos ahead!
