Sure looks that way. Phantom thought it still might be available by phone from the on-line store, but nerdboy tried to get it and said he was unsuccessful.
I was considering this too as our AP's expire on 8/14 and we will be at UO until 8/16. Best deal is to renew our AP for $99.95! However, with an active AP, it sure ends up costing a lot in extra trips!
