This is an absolute shocker for me and something I've never experienced at any hotel I've been to either domestically or worldwide (and I make a point of using all the in-room coffee in my room). That's about as low as I've seen a hotel go (other than not including coffee maker in the room). What's next are they going to charge for using shampoo, conditioner and other toiletries in the bathroom?
On a side note, Nespresso vs Keurig thing really depends on where in the world you are. IME if you're staying at Hiltons in Canada/USA, it's almost always going to be a Keurig since that's the predominant single serve coffee maker over here. It's also somewhat difficult to procure Nespresso cartridges within NA (i.e. you need to be near a boutique or mail order them in which takes time). The only exception I could see for this would be in larger metropolitan areas like SF, where the boutiques are close enough to justify. Outside North America, it's almost always Nespresso since Nespresso has a worldwide cult following whereas Keurig doesn't...I don't even think you can buy a Keurig brewer in Europe!
Safe Travels,
