American Hotelier Conrad Hilton introduced the Conrad brand in 1986 to provide guests with a more acute sense of luxury than what you'd expect to find at the more expansive Hilton Hotels chain. Positioned in the world's most popular vacation destinations — including the Maldives, Istanbul, Chicago and Puerto Rico — these high-class hotels strive to infuse local culture into their design and services. Though no two properties are alike, you'll discover such upscale amenities as state-of-the-art fitness facilities and fine-dining establishments at all Conrad hotels, while select locations also feature full-service spas. The brand even provides guests with custom (and sustainable) bath products, not to mention high-quality customer service. And while you'll pay more to bed down at a Conrad hotel than you would at other Hilton affiliates, you can use Hilton HHonors rewards points to cover nightly rates, room upgrades and a variety of other expenses, such as airfare and even souvenir shopping.
