OKW is the only place that has given us balloons and a card signed by Mickey-even though we've visited many different resorts for many different occassions. So it was a total surprise to us when, a couple years ago, I mentioned to the CM checking us in that we were celebrating DS FINALLY graduating from college. I told her since she appeared to be close to his age and would probably understand how happy everyone was. Lo and behold, the next day a bouquet of balloons and a card signed by Mickey. I don't know what it costs Disney to do this, but it was very much appreciated! So from our experience, you have a good chance at OKW.
