We will be at the WDW Swan for 3 days next week before we cruise on the Magic. We would love to ride Mission Space before our cruise. Has the operation of this attraction been consistent enough to "almost" assure us of a ride if we do a one day pass on Thursday, Aug. 7 or Friday, Aug. 8? How do you know if the attraction is opening for the day(Do you ask a cast member)? Your insights are appreciated.
