We took a Disney trip in January 2010 and the particular week we went they experienced record lows. We wore our winter coats from home for 6 out of 7 days of our trip, the top news stories were local stores running out of warm clothing and accessories like hats and gloves, stores running out of heaters, crops dying.
Anywho, we were at AK one of the coldest days. There were heaters around for the greenery and it was so cold that Fastpass machines were locking up, Everest was suspended, other things were closed, and we found ourselves in line for Primevil Whirl (PrimeEVIL Hurl) as it featured a 5 minute wait time. We figured, "hey we've never ridden this, might as well as not much else is working".
We waited in a halted line in the freezing cold because the ride wouldn't run, barely moving for an hour with CMs walking up and down the line repeatedly saying it would be running in 5 minutes. An hour later, we finally rode and I was a popsicle and wound up nauseous. Now that I am looking back, I have no idea why we waited in the line outside when we could've been in a warm store or restaurant. Lesson learned!
