Hi. If you're just doing the walkthrough of a ride such as Forbidden Journey, do you still have to put your things in a locker? I figure it's better to know in advance. Thanks!
Nope. You just tell the the team member just outside the lockers that you're doing the walk-through. They'll point you to the next team member, who will let you down a separate queue.
You can also do a separate queue walk-through of Gringotts. When we did it, we were able to see everything the standby riders saw--including the elevator and Bill's office--with our cameras.
We do child swap on the ride so everything just stays with the person who is waiting with the children not riding. Its great cause you can then take pictures of inside the castle
