I'm not sure if the southern levant (Eilat) Hotspot should exist as it literally states that St. Catherines area is no longer possible due to security reasons, along with that 3/4 require a major border crossing and are not possible by public transport
Yep. Borders are an issue with hotspots. See my comments re Suceava. Unless it's a green border, sites across real borders shouldnt be grouped into a hotspot. And public transport across hard borders tends to be limited.
Re Eilat: In peaceful times, I can see organized day trips having fast border transit. Peaseful no more.
Although I can understand the general point of easiness of border crossings, this really is a more common one than you'd think. Many Israelis visit the Sinai. There are numerous day trips on offer from Eilat, also when I researched a trip for April 2020. I will remove the comment of 2016, which isn't accurate anymore.
