Is your battery running out at the Park? We recommend this charger, it charge your phone 6-8 times (full charges), it is amazing http://amzn.to/vEV5VF (MW benefits if you purchase)
The master plan for the LAST day:
Open AK, ride Everest and dinosaur. Bus to HS, ride backlot and see Indy Show(maybe). Boat to Epcot, eat in world showcase, say goodbye to Indy and Marion. Maybe go to MK and meet Schramke :)
Then go home, clean and pack to wake up and leave at 5 am. Makes me tired just thinking about it all.
