I was in Epcot on Monday 10/26. At about 4:00 or so, Test Track showed a 60 minute standby wait and a 30 minute singles standby wait. I was surprised at the long posted wait for singles but figured it wouldn't take so long. My wife and I waited and it too a little under 20 minutes to get on.Not sure if anybody caught the Touring Plans series: http://blog.touringplans.com/2015/11/01/whats-up-with-wait-times-at-disneys-animal-kingdom/
One thing that stands out as being goofy right off the bat is the Expedition Everest single rider wait. Has anybody really waited 20+ minutes in single rider? Ever? I was under the impression that there were typically 10-12 people in line.
TP also showed a longer than normal singles rider wait time for Test Track and Rock n roller coaster. I think Disney is just being more conservative with their singles line wait times, but perhaps more people are reading the recommendations about using the singles lines.
