Someone who traveled with their mother-in-law who was feeling unwell.

I felt sorry for my mother-in-law who stays at home every day, so I suggested a trip, but she always refused. After repeatedly persuading her, she agreed to go with us. Now that she's actually going, I feel a bit worried. She can't walk much and has several chronic illnesses, but I want to take this opportunity because if not now, when else would we be able to travel together?

I am planning to go on a long drive mainly by car towards Gunsan, Shinan, and Saemangeum.

Please help if you have any travel tips.
