Wag Hotels, San Francisco

With up to 1,100 square feet of outdoor space, private suites, and splash pools, Wag Hotels would be a swanky destination for any human. But as much as they might want to—and as much press as they might have read about the hotels—bipeds aren't welcome to spend the night at either of the hotel's locations. Instead, cats and dogs rule the roost at these luxury pet resorts.

All locations are open 24/7 and offer more than 10,000 square feet of indoor playrooms where pups romp around. Spacious boarding rooms with flat screen TVs await canines spending the night while two-level kitty condos keep cats entertained with built-in exotic fish tanks. And for top dogs, Wags offers Ultra suites outfitted with raised Queen beds and in-room aromatherapy dispensed by employees. Animals can even indulge in the hotel's spa, which offers such grooming services as oatmeal shampoos and pet tattoos.

To ensure each four-legged guest's visit is comfortable, Wag's team employs the Wag Care 360 approach. This approach includes sanitizing the facility regularly and allowing owners to check in on their pets via the hotel's web cams. Wag also provides dog training courses.
