I'll 2nd, 3rd and 4th the Giordano's recommendation
Before finding out about Giordano's delivery, I once had a room-service pizza in BWV, and was stunned to actually get a darn respectable pizza from Disney !(winds up being the same as the Pizza window at Spoodles). Every other pizza I ordered at Disney parks and resorts has been the same bad thing that might be called a "pizza" at Chucky-cheeze),
but you can get a much better pizza for less $ from Giordano's
