Pure Luxury is my go to for all events that we need transportation for. I recommend them to anyone in town looking for a way to get big groups around - not only in the Petaluma/ Wine Area but even in SF. We've done several big group trips on buses, and the drivers are very professional, friendly, and always on time. Driving a 60 passenger bus thru the city is tough work, and they do it very well.
All the buses I've been on have also been very clean and well kept. They also arrange for smaller sedans and such as well. Definitely recommended to all.
