Transportation for guests?

My wedding is in a small town about 30 minutes from my fiancé and I's hometown. There is a local motel in this town that gets good reviews about a 10 minute walk from the venue and a few Air BnBs. The nearest chain hotel is 20 minutes away (in our hometown). There are a couple Lyft/Ubers around but not nearly as much as a city. We are having a cash bar at the wedding. My family doesn't really drink, but my fiancé's side does. I've heard online that people provide busses for their guests to prevent drunk driving, but I think this a regional thing because no one I know has ever heard of this so I'm not sure what we should do. We are in the Midwest. Honestly if I was a guest I'd rather figure out my own DD or just not get wasted so I could drive myself, I wouldn't want to ride with others.


On the invites I plan on listing info about the motel and AirBnb's in town, and the hotels outside of town. Is this a situation where we should provide busses? Most of our guests will be staying with family in our hometown anyway, so it's not like everyone will be staying at one hotel and I'm thinking it might be more of a hassle to coordinate than it's worth. I should also note that the ceremony and reception is in the same venue, so guests would only need to drive for that.
Also, the reason we chose this venue and not one in our hometown was because my fiancé is active duty in the military which means there's a possibility we'd have to reschedule if he gets deployed. This venue was extremely accommodating and said that we could reschedule without losing our deposit if this happens. We're only paying $1400 total, for all day Friday to set up, and all day Saturday!
