I think the codes vary by the city...you may want to add that to your post!
We're going to The Lion King when it gets to Des Moines next year...we did the package through a local hotel, and since DesMoines is about 6 hours away - we'll need it anyway! Best part - we've had our package reserved for weeks, paid for already...and we got great seats!!
Sorry...color me excited...I'l stop hijacking your post!
