Wawa! We have a ton of them near my university, so I definitely understand the appeal. There's no better spot at 3am for a sandwich and some coffee.
The mint chocolate chip cookie sandwich is a great idea! As for the orange dole whip, I have to say it's one of my least favorite WDW foods. Some people love it, but to me it tastes artificial and like medicine.

I think the citrus swirl is much better than the orange dole whip (and I'd gladly take a pineapple-vanilla swirl dole whip over the citrus swirl).
