Hi there,
Yes. Several of the tips are outdated. If you spot anything that needs to be removed, please let me know.
Walt Disney World is ever changing, and this document is HUGE. I have compiled it over years -- for myself and my family -- so that we could look for things while we were there.
However, that said, we started going many, many years ago, and so, yes -- many of the "secrets" are now outdated.
If you request the document from me (I am currently in the process of sending out a huge number of requests now), please let me know if you find anything that needs to be removed.
Thank you so much!
