Hiya Englenn!
Welcome to planDisney! You have come up with a great question as this is something I encountered myself! I was on the hunt for another guest to help find some planning videos and I bet I found the exact site you encountered. You are correct that it leads to nowhere. At this time, Walt Disney World does not have any planning videos for guests in the United States to have mailed to them. To be honest, there are so many changes every month in the Parks with new attractions and events that it's hard to sometimes keep up.
I'm sorry I don't have better news but there are still some great resources for you! The planDisney panel has a whole
video library to help you during this planning time. I'm going to link to this answer a good one for first-time guests that covers all the basics. I have also found the
Disney Parks Official YouTube page to have some great recent updates and fun videos that I like to watch with my family.
I especially want to make sure you check out the planDisney Walt Disney World
vacation planning checklist. The planDisney extras page has some great tips such as
Park bag essentials and
Walt Disney World Resort pocket guides.
As always, you are welcome to come back and ask us any questions you may have. I would love to
personally help you if you like as well!
Happy Planning!
