Well we started out this AM visiting Disney's California Adventure and after a few hours in that park we decided to "hop" over to DisneyLand,(we had purchased 5 day park hoppers) so we left the DCA. and walked over to DL. When we showed our park passes to gain admittance to DL,they would not let us in because "we did not get our hands stamped" when we left DCA. Anyone else know that you need a hand stamp ALONG with your ticket. They finally let us in after we showed them some receipts as proof that we had indeed been in the DL park. Has anyone else run into this at Disney California?
