I use a spray bottle myself, but then mine are in pots. It would depend on how much mist you need.
Leaves wrinkle when they die. I've always assumed that a plant too dry will sacrifice older leaves at the bottom/outside of the rosette to keep the inner growing core alive.
Wrinkled could mean rot or dying leaves from too dry. That's why I advocate misting. Misting will usually allow some water to run down the leaves to the base of the plant and wet the top of the soil. However, the medium will dry out rapidly because the deeper soil never gets wet. You are getting some small amount of water to a plant but not a whole lot, so you get to adjust the water/moisture content quickly in case you see rot. A tiny amount of water will keep the plants going, especially if out of the sun.
If out of the sun, and relatively cool, the plants can survive many months without any water.
Can you take another pic on Monday and post it? Watch closely. Rot can spread rapidly but too dry takes a lot longer to kill them. A little time should tell the story.
