When we were there (same time as Nick and Cindy) we just called in our order and picked up the pizza's at the pool's take out window. They were very good and reasonably priced.
When the resort first started serving pizza, most of it was the flat kind with wheat crust.
A CM said that they got a lot of complaints and a lot of guests calling out for pizza delivery. They now serve a normal style pizza and most nights Bleachers is open until 9pm.
They offer some nice family pizza packages that come with salad and drinks.
