My husband and three older children would like to spend a few hours at DisneyQuest. What I'm unsure of is if they need admission to the park and then the ticket for DisneyQuest on top of that, or if they can go to DisneyQuest without using one of our park days. I thought this would be a good activity for one of the "down days" if I could avoid using up a park day by doing so. Thanks!
