Going for holiday with family members who do not uphold the laws of deen

Q: We often go for long family tours in India and mostly we are in the bus. My family plays music in the bus so that the driver (not a family member) will not fall asleep and free mixing happens among cousins born in joint family. 

Am I allowed to join such family tours while observing hijab and closing my ears to not listen to music? If no, What should I do if my parents insist that I accompany them (it would cause them great sadness if I don't come)?

Purdah between non-mahram males and females

Q: My friend [24f] makes parda from her brother in law [17m]. However her father's first cousins is her husbands maternal uncles and she doesn't make parda from them. Upon telling her she brought the hadith of brother in law being death and said there is no specific ahadith relating to her having to making parda from her husbands mothers brothers therefore she doesn't have to. Is it true?
