10K Service Coming Up

We’re about 500 miles out from the 10K service on our e-tron and my dealer Audi Mechanicsburg has been reaching out to schedule a visit. Can anyone who’s done it already tell me more about how long it took and what to expect? I’m debating whether or not to book a loaner or just wait. It’s about a 35m drive, so going twice can be a time waster. I don’t mind working in their dealership as the new store is a great location, but I don’t want to be there all day.
