Great Wolf Lodge is having a 48 hour sale on rooms/waterpark passes on stays now through April 30, 2012. Use the code R48HOUR at checkout for big savings at the Grand Mound Great Wolf Lodge in Centralia, Washington. Discount prices start as low as $159.99/night for your room which includes waterpark passes (weekends, of course, are priced higher). There are certain blackout dates where the discount does not apply. Our family has been there twice and we love it! Sale ends Sunday, January 22, 2012 at 11:00 a.m. (PST). Check out the review that my kids wrote if you want to learn more about the Great Wolf Lodge.
