I really hate it when people suddenly become an expert on the CP by just showing up in Florida. MEO has 3 separate aspects to it. Doesn’t matter "what you’ve been told", it is on the official site. Ticket Ops is in the water parks.
that is true about tickets, I forgot about it because far less CPs end up there, especially in the fall as one water park closes during our time here.
As for MEO at the parks, a manager told me that, at Epcot at least, CPs who are Park Greeters will NOT be cross trained in parking because it is a separate union. We can, however, be cross trained in Auto Plaza. I can tell you that from my experience so far there is no one who is hourly that is trained in both parking and turnstiles unless they are of coordinator level or higher.
