The tram speil is confusing. I believe it states that the tram will run 2 hours after DTDs closing, but to check individual locations as closing times vary. If I remember right, after that it says the parking trams run intil 2am (given this is a weekend when the parks are open till midnight)
Well, a little known fact but after the trams go off service the disabled people buses continue working because of World of Disney CM's and others that park out behind the structure. I am sure if the trams aren't working you can catch that shuttle. But why would the tram time even be a problem? I mean who stays at the park until 2:30 in the morning unless you're a CM?
