Trading UP

[fasttrakphil]

I Am Thinking Of Upgrading To An Annual Pass This Next Visit. My Question Is I Have Many Old Passes That May Have A Day Or Two Left On Them, Some Maybe More Some Maybe Less. My Main Question Is Can I Trade Them All In Towards The Annual Pass And Is It Rude To Ask A Cast Member At The Ticket Center To Check All Of These Old Passes For Their Value Or Lack There Of?????????????
