Are all sales final? Do they have a cancellation policy?

From their website: "WHAT IF I NEED TO CANCEL OR RESCHEDULE? Not a problem! Your E-Mail confirmation has an orange button on it that says "change reservations," which can be used to cancel or reschedule your game. Full refunds will be granted for games canceled 24 hours or more before the start time of your game. We can not grant refunds with less than 24 hours before the start of your game."

They are one of my favorite escape rooms in northern California
