There are multiple options for transportation depending on where you're staying. As far as I know, there are no shuttles that go directly from a hotel to the fest but there are other shuttle and ride options. www.oktoberfest.org has lots of information about how to get to the fest.
Justin, no shuttles except early evening to the Silverton area. Uber, taxi and Lyft drivers abound
No. Only shuttle during the event, is from downtown to the Abby. Well worth the trip!
