UPDATE: BB/BS has sold out of the day passes that they had. Looks like their fundraiser was a success!! Hopefully they will have one again next year. Here is the info from the BB/BS website:
Due to an overwhelmingly supportive community, Great Wolf Lodge day passes are no longer available. We thank you sincerely for your interest and hope to be able to offer this same fundraiser sometime in 2010. This will depend on the continued generosity of Great Wolf Lodge.
If you live in the Dallas/Fort Worth area, there’s a GREAT deal on day passes to the Great Wolf Lodge in Grapevine, TX.
The Great Wolf Lodge normally does not offer day passes, although those who are staying the night can invite guests to swim for the day for an additional $40 each (yikes!)
BUT, the Great Wolf Lodge in Grapevine, TX is offering a special deal to benefit Big Brothers Big Sisters. Order your tickets from BB/BS HERE and you can get day passes for only $15 each. You have to use your pass before Dec. 18th, and it’s not valid during the Thanksgiving Holidays (Nov. 24th – 27th). AND, all of the proceeds go to benefit Big Brothers Big Sisters! 
We got to check out Great Wolf Lodge this past May and our whole family had a BLAST!
(Thanks, Craving The Savings!!)
