Guatemala is the most underrated country in Latin America.
Tikal is one of the best Mayan sites.
I enjoyed my visit a few years back https://ashishb.net/travel/guatemala/
It is an underrated country, I remember that after Tikal I ended up at ChichenItza and it just felt boring (and way too touristy) compared to the lush jungle beauty in Tikal and Yaxhá.
Yeah, Chichen Itza has its pleasure of being a comfortable but touristy place. Tikal is much better for travelers, though.
