Yes there's good parking. It's a great Hotel. Marriott is the best! At the courtyard, it's quiet and at the same time close enough to even walk nearby restaurants
The parking lot only has one long entrance but a ton of parking that never gets too full, and a security guard that patrols the parking lot at night. The parking lot does loop around the hotel, but it may be a bit narrow at the corners for a bus. I would personally pull in front of the hotel and the back up to park. If you still are concerned, look at the satellite image.
There is a long entrance with parking on both sides it could be possible to to park long ways them back out into the street.
