I’ve taught English in the Gulf, in Qatar and spent a bit of time in the Emirates. This was 4 yrs ago so perhaps some things have changed.
First off they have no way of telling who’s Jewish and who isnt’ unless you walk around with a Star of David or something. In one memorable incident in school a student asked me if Abraham Lincoln was Jewish (beard, named Abe, black suit…). The Three Stooges are pretty big with some of the guys so I could blow minds by sharing the fact those guys were Jewish. And so on.
In theory they bar people who have Israeli stamps on the passport but I wonder about this. Odds are they wouldn’t even notice at passport control, I don’t recall them looking at every page of mine, or even most. I met Israelis in Qatar who worked at the trade office (i.e. the embassy-that-isn’t-there-but-actually-is) and I’d be surprised if the UAE doesn’t have something similar. So who knows.
THe UAE - or at least two of the Emirates, A-D and Dubai, are all about tourism. The other countries on your list not so much, although there are moves in that direction, especially Qatar which has a few nice hotels now and is rapidly investing in over the UAE style pleasure palaces.
When I lived there, on a free (for me) work visa, a tourist visa was US$300 plus you had to have proof of reservations at the approved hotels, which were the expensive ones. I imagine this is chagning.
Honestly there’s not a whole heck of a lot of diversity between the Gulf States that would warrant being a tourist between them. A person can only see so many opulent new hotels, sand dunes and corniches. Qatar has some limited remaining traditional charm but that could be found in one of the more conservative Emirates which is much like going to another country in some ways.
Honestly A-D and Dubai are the party locations of the Gulf and most people in the other countries are trying to vacation there! Bahrain is also pretty open with its alcohol/nightlife policy.
I would suggest taking advanatge of the relatively cheap flights out of the Gulf to explore somewhere like Isfahan, Kathmandu, Trivandrum, Lahore, even Bangkok. I went to Nepal with my vaca time, as well as the UAE.
If she does try to get to Qatar, which is half the size of NJ, have her email me & I’ll give her the list of everything to see in the country, which should take less than a week…
