The Great Wolf Lodge, located just off the I-5 freeway, features an indoor waterpark (kept at a constant 84 degrees), hotel rooms designed for families, crafts and activities for kids, a kid spa, kid-friendly restaraunts and more. A special toddler area is designed for the parks youngest guests and monitored by lifeguards (but you will still want to keep your your young child at arms-reach). Older kids can enjoy the park more independently with kids age 12 and up able to enter their room on their own using waterproof wristbands.
The waterpark and rooms are all clean and well maintained with an ample supply of lifejackets and lifeguards on duty. This is a popular destination for locals traveling from nearby Seattle, Portland, Olympia and Vancouver and can be crowded, especially on weekends and holidays.
I received a complimentary stay at the Great Wolf Lodge for review purposes. I received no other compensation beyond the room water park passes, and the resort did not require that I express a particular point of view.
