Like to travel with your pet? How about really traveling in style? Some luxury hotels are going out of their way to make visitors and their four-legged companions feel welcome.

The Four Seasons in Washington, D.C., is one. Their room service will even deliver your pooch's favorite dog biscuits on a silver tray. The Ritz-Carlton in Chicago also is happy to pamper pets. On each visit, they'll provide your pet with a linen pillow and a squeaky toy or personalized dog biscuit. Plus, there's an on-site kennel to handle any grooming needs, and the concierge will take your dog for walks.

Of course this doesn't come cheap. But more first-class accommodations are happy to offer this service. The reason? It's simply smart marketing. People today are traveling more with all family members, including pets.

So, if your future plans include a stay at a four-star hotel, you won't have to leave your pet at home. But be sure to confirm that pets are still welcome. Now, where's that waiter with the liver tidbits?
