What time do buses start running from the Contemp to MGM?

[Spoisal]

I think MGM opens at 9am, but I would like to make an earlier breakfast PS.

Regular buses for day guests will start running at about 8:15. However, starting between 7:00 and 7:30 they run a few buses through the resorts for guests with breakfast ressies in the parks. These buses are marked "Character Breakfast". The bus driver won't ask to see your PS confirmation, but you must show it at the park turnstiles.
