I received an email code today. I currently have an October trip booked and paid for using the ZBH code that came out a few weeks ago. Can I call Disney travel and see if the email code is a better deal than the ZBH code? Since it's already paid for I wasn't sure if this was possible. I think that I've heard that basically you would be canceling your existing reservation and starting new. Would this just confuse things? Any advice would be appreciated. I've never been in this situation before and would love to save some more money but don't want to mess things up. Thanks so much.
