I suspect weather forecasts of rain for the whole week had something to do with it. A family sees rain in the forecast, and doesn't want to waste a day with $200 on the line, and the kids won't get dropped off if the parents think lightning is in the area. Sometimes, you get rewarded for picking "bad days" to go, and sometimes not so much. I'm glad everything worked out for you.
