It says that she left her hotel at 9:53, not the conference. It sounds like she blew off the whole last half day, slept in and went straight to Disney World.
Which is worse than skipping out an hour early.
typically conferences like that are at the hotel especially in Orlando
I am not excusing her
but to leave a conference on last day an hour early is not a huge deal.
The important seminars and talks would have already happened.
Her charging taxpayers is a big deal
