Hi everyone, I am trying to book 6 tickets from Paris Gare de Lyon to Basel SBB but noticed that I am not able to pick the specific seat for the seat reservation. I am only given options such as “Lower/Upper deck”. As my family has vertigo, we will be susceptible to motion sickness if we are facing the reverse direction of travel. May I ask if there is any way to make a special request for this matter? Thank you!
