The conversation about Photopass in the Luau & Hoop-De-Doo thread got me thinking about one thing that I really don't know why they don't do at WDW:
Put everything on my room key.
I love that I can have my charge card on there, but as an AP holder I can't have that function as my room key. Also, why not let that work for Photopass so you can just keep all that stuff together. It doesn't seem like the technology would be that hard and then I could basically leave everything but my room key behind all the time.
