Right! It's a room right in front of the Elite Travel glass hut. It's marked with a white sign with a little green tornado on it that says tornado shelter (or something similar to that, anyway; seven years here and I haven't ever really looked at the sign). If you go in there, though, you're probably going to wonder ... is going on because it's just a hallway that leads to the kitchen area for the hotel restaurant and the service elevator for the hotel, along with the hotel workers' break room. Another door, about half-way down the hallway, has the same sign on it, and if you open it you are then presented with an area right out of one of the Saw™ movies. It's a confining, narrow, steep concrete staircase that spirals down in hard angles, and once you're down there, you're basically left in a dark concrete room that the hotel has almost completely taken over as a laundry room. There's still enough room to legally use it as a storm shelter, I suppose, but it'd be a little odd going down there and you're surrounded by steam cleaners and crap. Pack a hundred people in there (about as much as I would care to try to squeeze in) and things are going to get toasty awfully fast.

The other tornado shelter is on the far side of the building, but it's entirely for airport workers, since it's actually located inside the SIDA, underneath gate three.

Yeah, it wasn't very optional here in HSV when it happened. Public safety rolled through in person and basically told everyone to drop everything and GTFO. The passengers, the gift shop workers, the restaurateurs; everybody.
