So I made an ADR for the Play and Dine place in MGM at 8 a.m. The park opens at 9 that day. But if I understand it correctly, the buses don't start going until 7:30. We are staying at the Poly. How are we supposed to get there?
They will have a bus running to MGM for the early reservations. In order to make sure you catch it, you will need to be waiting for it probably between 7 and 7:15. You can ask at the conceirge desk in the lobby for the exact details though.
