If I buy an AP now, but don't plan to go till early September, can I book my resort with an AP discount if my AP hasn't been activated? We haven't had an AP in many, many years but my DD was accepted into the Disney College Program for the fall, so I'm guessing we will be going a lot! I seem to remember we could book our resort without activating our AP, but wanted to check to be sure. Thanks in advance for the help!
