Well there's always the hidden mickeys to look for. Aside from that I'm really not entirely sure what's new there. If you haven't all ready, might I suggest reserving a dinner at the Hoop de do Revue. It's a reeally fun western saloon style dinner. There is a show and the food is amazing. There's also the 50's prime time cafe in Hollywood Studios that is interactive. Perhaps while you're there you could ask a cast member what else you can do. Hope this helps.
