There’s a problem with most airport hotels: Proximity and convenience tend to come at a price, and you can usually measure it in decibels. This makes it all the more astonishing what the clever engineers at Marriott have done here. The Renaissance Concourse Hotel is something altogether unprecedented: an airport hotel that sounds like a secluded woodland cabin. This is acoustic science at its best, and the best part may be what you don’t see: walls, insulation, shielding or baffles. The Renaissance boasts huge windows and an interior atrium 22 stories high. It’s nothing but space and light, all wrapped in a cutting-edge aural cocoon. No wonder people come here to do business and end up surprising themselves with a perfect night’s sleep. A $4 million renovation has been put to brilliant use throughout the living quarters. The rooms boast inviting designs in cream, sea foam and cherry wood – stunning enough to earn a prestigious fourth star from AAA. Elegance comes in tiny, unexpected doses, such as a bud vase with a single peacock feather on your room service tray.
