<human>: Give me the gist of the text in a nutshell

My parents are in Russia until next Friday.  When they go overseas, they are super hard to reach, and we basically never hear from them which is normally fine.  Last night my sister and I found out my mom's favorite niece passed away suddenly.  

I am having a really hard time deciding if we should try and find the hotel my parents are at and tell them.  On the one hand, I know that they could not come back in time for the funeral and there is really nothing my mom can do at this point.  It seems silly to ruin the rest of this awesome trip.  On the other hand, I do not know if I should keep this from her until she gets back.  I also am the one picking them up at the airport and have no clue how and when to tell her after such a great trip.  

Just looking for some advice: would you wait until they get back or try and reach out?
<bot>: My mom's niece died but she is overseas and can't make it back for the funeral.  Should I wait until after the trip to tell her or try and contact her now?
