"There's a lot of open space on the ground floor," Lou told the group, in case any of them happened to be unfamiliar with the layout of the Casino. The ground floor held the games, and the only properly closed-off areas were the apparition closets and the floo rooms. "So we should at least be able to see — if there's anything to see. If we have to go up, it would probably do well to have some sort of strategy for clearing areas." There were plenty of nooks and crannies in the upper floors, he thought. He'd never actually partaken in any of the other novelties at the Casino, so he wasn't entirely sure, but many of the things they'd offered didn't sound like they'd necessarily take up the entire floor, like the games on the ground did. He certainly didn't want to get into a situation where they had something like the Sphinx sneaking up behind them because they hadn't been paying attention.
