We did early ticket pick up in December 2010 with no problem. We had 2 nights room only at AKL before changing resorts where our package started. We went to guest services at Animal Kingdom and within 5-10 minutes we had our park tickets in hand and were inside the park
. The only thing we ran into was after we checked in for our package. We were told our "early" tickets could not be added to our new KTTW cards, which was fine since we anticipated this from reading the tickets sticky. However, once we checked in for our package, our early tickets were somehow deactivated (which we weren't aware of) and our park tickets were indeed on our new KTTW cards. We found this out when we went to DHS later that day and were denied entry due to our early tickets being "upgraded". After a quick trip to guest services, we found out our park tickets were on our package KTTW cards. Other than that small glitch, everything worked great
