I bought cheap(er) lanyards on amazon to bring to park. You can get online, in your local mall (spencers), in park, in onsite hotel stores. Make sure they have the clear plastic holders for express pass. I honestly don't know how much they are on property....my guess is $20 or less. Also, if you are going on Hogwarts express you will need to show your entry ticket (park to park) to get into line. I kept both park ticket and express pass in the lanyard (and hotel card key) since this is about all you'll want to carry in the park (locker-ing bags is a pain, though you have to do it for cell phones on some rides).
