There is another nice offer for Great Wolf Lodge if you have been wanting to go. We went over Christmas and the kids LOVED it. It was very fun! If you have never been it is basically a huge water park inside a hotel.
It is such a nice activity for the winter months when everyone is cooped up inside. Prices start at $259 and vary based on which location you choose. Some packages are for a one night stay and others for two nights. You get water park passes and some include resort credit to use during your stay.
Head over to Groupon to take a look. Most of these have to be used by a certain date and some have blackout dates. Just pay attention to all the fine print.
Daily resort fees ($14.99/day) are not included in the price.
