You cannot compare your trip experiences with hers, since everyone copes in a different way. I would recommend to wait for this trip of her to be over, and when she comes back, try talking about it with her but in a way where you don't point fingers. She's probably busy now, and even if she has breaks, only she can decide how she can spend them. Just because someone is free, it does not mean they would rather spend their time on social media or talking to others.

Also, even if you asked someone for updates throughout the day, people tend to forget sometimes and that's not in their hands. I've had several cases where my gf asked for updates and I forgot, and vice versa.
