Not long ago I played SP21 at a casino where I had not played in a long time. Table was empty. I asked the dealer if I could play 3. He says, "You can play all of them if you want." In a few minutes with 1 other player on 2 spots, I tried spreading to the other 4. "Whoa, just kidding," he said. But he and his replacement let me play 3. Is this common in AC? (I've played 2 other places and they both limit players to 2 boxes.)
