And how secure are we if strangers can make deliveries all over property , and yet we are xrayed and rooms inspected as if we are the security threat Disney is searching for!
Hmmm. I've actually never been x-rayed at WDW, nor have I had my room inspected.
On the question of Uber/Lyft drivers being allowed access to WDW, some of that is state law. If Disney allows taxis, car services, shuttles, etc access, they can't legally keep Uber out.
In addition to that little legal constraint, Disney also
actually enjoys having Uber/Lyft bringing visitors to WDW from off-site. The Mouse is not going to prohibit people being brought to their property to spend money.
Also a part of Florida law is the very stringent requirement for a very detailed background check for all rideshare drivers. It is MUCH more strict than what taxis, car services, etc provide.
In addition to the state requirement, Uber does two more things -- they re-do all driver background checks annually, and they have an independent company that provides continuous public records monitoring and reports any arrests or other legal issues to Uber for investigation.
Visitors, of course, are not required to have any background investigations.
