A few questions. Im headed out to Stuttgart. Hows the drive from Frankfurt to Stuggart? Anything interesting along the way to see? Likely will have a rental car. Anything i need to be aware of? Should i consider a train instead and grabbing a rental in Stuttgart? If i go the train route, can i buy a ticket on the spot or do i need to reserve in advance? Are they flexible to change?

Also what is the restaruant scene like in Stuttgart and Frankfurt? is stuff mostly open? Whats the mask protocol around town and such?

Thanks!
