Universal pick up to busch gardens

[Orchid]

This has been asked elsewhere but just asking again incase any new people know. Has anyone taken the free bus to busch gardens from the universal first stop? I'm wondering if there is place to park our car there or do we have to park inside universal to catch the busch gardens bus. I'm not familiar with this so not sure which stop to catch. Should imagine this bus gets busy so was hoping to get it here rather than a later stop.

When you reserve the bus, is there only one time that the bus returns to take you back or are there a few times and you reserve for one time?

Thanks if you know and have any comments about taking this busch bus.
