Exclusive Feature: With so many luxury hotels on the market and in your favorite cities, how do you choose where you stay?

That's been the focus of luxury hotels for years -- how to make themselves stand out from all the others and be the number one choice for guests, in any city.

Over the years we've seen some impressive and creative amenities launch from luxury hotels -- in-room virtual personal training, celebrity chefs, personalized welcome amenities and even Twitter butlers (for those who can't find the time to tweet on their own).

But one thing remains constant: service, above all, is the ultimate luxury amenity. And according to a recent survey of affluent luxury travels, one hotel group stands above all when it comes to service.

According to The Resonance Report, Ritz-Carlton is the luxury hotel brand preferred by more affluent travelers than any other. While 26% of luxury travelers report having stayed at a Four Seasons Resort or a Ritz-Carlton resort while on vacation, more survey respondents say Ritz-Carlton is among their "top 5 choices if available" by a significant margin.

The Resonance Report on Affluent Travel and Leisure surveyed more than 1,200 U.S. households with incomes of more than $150,000 USD in partnership with the Luxury Institute to evaluate their plans for travel, recreation and the purchase of vacation homes in the next 12-24 months.

"It is interesting to note that travelers under 55 consider luxury brands such as Ritz-Carlton, Four Seasons, and even august brands such as Waldorf Astoria and St. Regis, more desirable than travelers over 55," says Resonance Consultancy President Chris Fair in a press statement. "Luxury clearly has not lost its luster with younger affluent travelers and luxury brands are, in fact, considered more desirable than contemporary brands such as W Hotels."

So where do the other brands rank? Here's a look at the top ranked hotels by group:
