The "do not disturb" signs on the doorknobs of Westin Hotel rooms perfectly express your state of mind: I can't come to the door just this minute. I'm in heaven. In two sturdy Cupple's Station workhorse warehouses, across from the endangered Busch Stadium, sits the newly renovated Westin, a modern hotel designed in the style of some of the most state-of-the-art in the world. Its hallways are architecturally wondrous, filled with the work of some of St. Louis' most respected artists, and the décor is simple and clean. Unlike most hotels, in which thedécor of the lobbies and hallways is so depressingly bland and inoffensive that it's virtually invisible, the actual trek through the Westin is a joy. But the real treat is upstairs, in the room. For $129 a night, you get a spalike bathroom, cordless phones, lighted makeup mirrors and marble, marble and more marble. Quick -- jump into bed. The cotton sheets have such a high thread count that they feel like silk. The pillows are filled with down; the comforters are mushy. Falling into bed is like floating in a cloud. One problem, though: Once in, it's hard to get out. Seriously. But it's worth it, especially if you're an insomniac. An amazing night's sleep is worth a hundred and some change.
