So…I just got an email from DIS:
There has been an unexpected change in the operating schedule of an attraction or show during your upcoming Walt Disney World® visit. Your FastPass+ selection for Splash Mountain from 8:55 PM to 9:55 PM on 07/21/2018 is no longer available.
As a replacement, a new selection was made for Splash Mountain from 4:55 PM to 5:55 PM on 07/21/2018.
My first assumption was Splash was going into refurb - odd timing, but obviously not as it is running at 5PM that day. Is it due to Magic After Hours that night? or??? Any thoughts? Not a big deal as we’re attending MAH that night anyway so we should be able to ride it to our heart’s content that night anyway, but it just seemed very odd. I’m guessing they’re canceling FP in the last hour prior to MAH to make the switchover cleaner, but that’s me making stuff up…
