We loved it. I'm learning arabic on Duolingo now because I got curious about the script.
Of course, YMMV.
We bought tickets for the Petra by night show, and while it was good, we felt it was a bit expensive for what it was.
The martian landscapes of Wadi Rum were equally as good.
We had two full days there and it was such an extraordinary site to look around.
And I'm pretty sure there were about 5 "Best view in the world" :) Although all of them could make a pretty good claim to the title, it's a stunning area.
I know it's not a perfect country, but to us it felt safe, in the way that some other nations don't, and we weren't confining ourselves to the usual tourist spots of Amman, Petra, and Wadi Rum, but also wandering further afield besides. Yet I've felt more at risk in parts of Europe, Russia, and China.
I just checked some global indexes and was not surprised to find that Jordan ranks #1 for literacy and medicine in the region, despite being one of the nations without oil revenue. In my experience it carried itself with the patina of both storied history and modern education.
