This happened to us with FEA on Wednesday. Our return time was 12-1 and we got notified through
MDE & e-mail that the ride was down and then it listed our options (return to FEA at a later time that day or use the FP for a different experience.) We had no intention of using it for anything else. We decided to hang out in the general vicinity of FEA starting at 12:00 and keep an eye on things so that when it opened we could get right in line as we knew the FP line would build quickly. At about 12:40, we noticed via the app that it was up and running again so we hustled over and got in line. We had about a 30 minute wait. By the time we got off the ride, they had closed the standby line and the FP return line stretched through the African Outpost and almost all the way to Germany. I'm guessing those people had about a 2-hour wait.
