John: Certainly 2, I haven't done it because I like cooking one at a time, but you could definitely fit two at once. If you knew what you were doing and could move quickly and delicately enough, I think you could shoe-horn 3 in there, but it would be tricky until you were used to doing it. The 950B actually is a bit over the 95 cm it's supposed to be (at least mine is) and mine is 39" which is a nice size. Because the dome is so low, it cooks very efficiently (once you get the hang of it) and doesn't require a ton of flame to have the flame going nicely across the dome. I could lay out plates in there (while it's cold) and take photos to show you if you'd like - I know where my coals would reach to, and what is my cooking surface, so I could see how 3 would fit that way. I usually cook 14+" pies and I know I could fit two in at once, probably not 3...
PizzaVera: Thanks so much for the kind words!! I will take photos of the dining room wall and post them later.
