Just a couple of updates…as of May 18th, the time at which you can first make FastPass+ reservations when the booking window opens has shifted from Midnight to 7:00am ET. Good news for the East Coast and Europe – not so much for the West Coast. We confirmed this change this morning.
Also, I’m hearing that at least at a few attractions there is a slight modification of the Rider Switch procedure, which adheres to the original idea that the Rider Switch pass should be given to someone going through the line first, insuring that it can’t be used until they return.
What may happen is that instead of being given the Rider Switch pass at the entrance, you instead get a lanyard that you will trade in further down the queue (likely at the loading area/merge point), where you will receive the actual pass. Nothing else has changed – the pass is still good for any three guests to use any time later that day.
[Update 8/4] I can confirm that the Rider Switch change has taken place at least at some attractions, as we used it and were presented with a card on a lanyard similar to the timing cards, and you trade that in to a CM further in the queue for the actual Rider Switch pass.
