What Additional Charge Experience or Service would you like to see?

[MJ6987]

I see that WDW is adding an increasing number of "plus" experiences or services that you pay extra for. Like the many Dessert Parties, the Eat / Drink around the Monorail, tours, the express bus service, etc

What realistic experience or service would you like to see offered and how much do you think it would cost? And would you pay that cost?
