I havent been to Poly for breakfast, but we did DB at AK last trip and we all agreed - totall waste.
The were seating an entire section at a time, which is a really bad idea. You're talking 6-8 tables at once and everyone going to the bufffet at once. Yikes.
Also, the food, I thouht was subpar. Not very many choices and even the standards were blah.
The only reason I could see to go to AK is to be in the park early for EE opening.
Trust me - stick with Poly.
