We ordered our APs in July (about a week before the prices went up in August). I tried calling to order TIW and was told you can't get TIW using your exchange certificates - you have to have an actual AP.
We picked up our APs at Epcot in October (be sure to bring
DVC ID to get the DVC discount - needed for both purchase and exchange certificate redemption). Got our TIW card at Guest Services. The TIW cards are no longer the plastic credit card style. They are now printed on the same paper as the APs. Part of Disney's greening initiative. The CM we spoke to wasn't familiar with the new TIW term - had to ask for a DDE card. I was glad to see we weren't the only ones struggling to pick up the new jargon.
