I just fished out my confirmation #'s and I had chosen the 'pick up my tickets at an Electronic Ticketing machine' option, and it says '2 park unlimited adm.', which if I remember correctly was the 7 day unlimited, I bought two one adult and one child and both cost the same amount---$86.98. When I check into RPR, and give the name of the kids, do the kids key room look any different than the adults? If not, then I guess using the child's ticket would be okay???
