I'm not sure if it's the same type of thing, but for ds's baseball tournament at WWOS, we had a package (for example: 4 day/3 nights stay, 3 day park passes, price based on 4 people per room) to which we could add extra days or add on the hopper option. We also had a contact at WWOS for our group who took care of our arrangements. So if there is a package, the tickets could be part of that.
