People turn to me at work on a daily basis and say similar things...but it's laced with the suggestion that I should make them cake.
I don't know if this helps, but these are the off site bakeries a lot people use if they want a cake at WDW, but don't want to deal with the limitations of the Disney bakeries...
Anna Cakes
Bake Me a Cake
It's Tasty Too
Sprinkles
And if you're ever in south FL, my parents swear by this place...

While not a WDW cake or even a Disney themed cake, this is a large verion of their Opera cake...
You should have seen the massive version they did for my brother's rehearsal dinner! YUM!
