Keep in mind that driving in Switzerland can be very slow (speed limit is often 80-100km/h), and in Austria you'll have tolls on some tunnels on top of the sticker that you need to purchase.

My wife and children are super excited about Neuschwanstein and Hohenschwangau. I am interested in driving Furka, Grimsel and Susten Pass.
Last year, I did one day Interlarken group tour from Zurich and traveled from Zurich to Venice (I was not driving). I wanted to comeback with my family.
I have 15+ year driving experience both in USA and South Korea. I am not planning to drive in Rome but I think I can handle rural area driving.

Initially, I thought about going east to Croatia and Hungary.
After reading Hertz rental terms, I dropped the idea.

"Hertz vehicles cannot be driven into and/or dropped off in any African, Asian, or Middle-East countries, nor in Albania, Armenia, Azerbaijan, Belarus, Bosnia-Herzegovina, Bulgaria, Czech Republic, Estonia, Georgia, Greece, Hungary, Kazakhstan, Kyrgyzstan, Latvia, Lithuania, Macedonia, Malta, Moldova, Montenegro, Poland, Romania, Russia, Serbia, Slovakia, Tajikistan, Turkey, Turkmenistan, Ukraine, Uzbekistan.
Hertz vehicles may be driven into but not dropped off in Finland, Ireland, Norway, Sweden.
Hertz vehicles may be driven into and dropped off in Austria, Belgium, France, Germany, Luxembourg, Netherlands, Portugal, Slovenia (Ljubljana only), Spain, Switzerland, United Kingdom (islands not included).
Hertz vehicles cannot be driven in any of the East European countries with the exception of Croatia where the transit only is allowed with written authorization which is given at the time of pick-up and attached to the rental agreement. Moreover Hertz vehicles are not allowed to be taken on ferries from any Italian Harbour with destination Croatia."
