Recent Developments

     On September 12, 2005, we announced the formation of a joint venture to develop Great Wolf Lodge resort in Grapevine, Texas, at the intersection of State Highway 26 and Business 114 across from the Gaylord Texan. We will operate the resort under our Great Wolf Lodge brand.

     The six-story, approximately 400-suite resort will provide a comprehensive package of amenities and activities. Planned amenities include a 80,000 square-foot indoor entertainment area, family restaurants, an arcade, gift shop, confectionery, spa, fitness center, and outdoor recreation area. Construction on the 400,000 square-foot building is scheduled to begin spring 2006 with opening slated for summer/fall 2007.

     We also announced an updated schedule for projects currently underway or planned, as follows:

	—		Pocono Mountains, Pa — 401-suite resort, target opening October 2005.
	—		Wisconsin Dells, Wis. — waterpark expansion, target opening March 2006.
	—		Niagara Falls, Ontario — 404-suite resort, target opening spring 2006.
	—		Williamsburg, Va. — 100-suite expansion, target opening late 2006.
	—		Mason, Ohio — 404-suite resort and a 40,000 sq. ft. conference center, target opening late 2006.
	—		Chehalis, Wash. — 317-suite resort and a 30,000 sq. ft. conference center, target opening spring 2007.
	—		Grapevine, Texas — approximately 400-suite resort, target opening summer/fall 2007.

     The expected opening of the Chehalis, Washington, Great Wolf Lodge project has been postponed until spring 2007 because of delays in transferring the land into trust.
