Play: Seattle makes traveling with dogs as easy as not traveling with them. The city has more dogs than children, 11 off-leash dog parks, over 30 different dog Meetups, and 45 pet-friendly hotels. On top of all that, buses and ferries, like the Bainbridge Ferry, allow dogs on board. In Sand Point on Pontiac Bay, Warren G. Magnuson Park has an off-leash section where dogs can swim, while Golden Gardens Park has a big off-leash area and spectacular views of Puget Sound.
Stay: Situated near Pike Place and pet-friendly Olympic Sculpture Park, Alexis Hotel (from $260/night) allows pets to stay for free and offers treats, food and water bowls, and designer dog beds.
