I want to travel from Paris to Interlaaken by train. www.sbb.ch gives me two options. With both, I first go to Karlsruhe. With the first option, I change trains in Basel Sbb with only 6 minutes to change (don't see the platform details yet). With the other option, I go directly from Karlsruhe to Interlaaken, but it takes 1 hour more. If there is no risk at all of missing the Basel to Interlaaken train, reaching one hour earlier is tempting. I will be traveling light, but will have a 8 years old with me. Any advice? Are there train options other than those I see on sbb.ch?
Thanks a lot.
