I need to be in Coburg for two days in mid July for research purposes.

Current travel plan is TXL-NUE (Eurowings) and then onwards to Coburg via rental car.

1. Considering the idea of taking the ICE train from Berlin to Lichtenfels so I can check out Leipzig while enroute. Does Lichtenfels have a rental car agency at the station?

2. Any hotel, restaurant or sightseeing recommendations? Callenberg is on my must-do list.

3. How about suggestions for finding a local translator as I may need research assistance at the Staatarchiv.

Thanks in advance.
