Disney Parking Lot Tram Operation Question?

[Elias1901]

Just a quick question. I am curious as to when the trams from the parking structure begin service? Do they begin like an hour prior to the earliest park opening? Do they take Magic Mornings/Extra Magic Hour into account? Any advise on catching the first tram of the morning would be welcomed! We are early risers! I've never needed to use the tram before, but I will be on my trip on December as I will be using my vehicle to get to the parks.

I couldn't find any information about the specific operating hours for the tram, but the Mickey & Friends parking lot opens one hour before regular park opening and 90 minutes before regular park opening on mornings with MM. I would guess that the trams are running when the structure opens.
