Travel from Ulm Germany to Austria/Switzerland

We are planning to take our son to a school term in Ulm, Germany the first week of October. We have been to Frankfort before and drove to some of the southern Germany destinations - Baden, Black Forest, Rothenburg. Looking at the map, it would seem that travel to Switzerland, Austria would be best. Not sure if it is better to rent a car, or are there any guided tours available, and what should we make sure we see. Would appreciate any insight. Thanks.

Neenah, are you asking for recommendations on what to visit while you're in Ulm? Or if you prefer send me a private message...

Best regards,
