just recieved my confirmation today for my 10 day world pass tiickets from the uk. I just noticed that mary says they are no longer allowed to sell them to the US. but she also says that people who have already recieved them can go ahead and use them and its alright with disney. has anyone purchased these and have you used them? have you had any problems. im concerned because thats a whole lot of money to just throw away!! thanks mimimom
