@pondypandy I believe the men who study for a living get a small stipend from the kollel. It is definitely not enough to feed a family and the wife has to work in most cases, but I also heard its a thing for parents to support their young married couple for a year or two (this may be more US centric).
I know more about the orthodox way of life because i lived with my DH's family who are frum. I wasn't Jewish when i started but by the time I moved out after 3 years, I was Jewish (though I did seek out a liberal synagogue to do my conversion). I was very immersed in the Jewish way of life, celebrating all the festivals, I was there every shabbat dinner, helped out with passover cleaning. I had to learn all the laws of kashrut and shabbat. My hebrew is a lot better than most reform jews because there was no transliterations in my MIL's house, you learnt hebrew or you sunk. I was like a orthodox Jewish child, except that I had to learn it in my 20s. So I have insights into both denominations. I think its an unusual situation to be in.
Camping holidays are actually a good option for the orthodox Jew. The main problem is not the synagogue service (as you can pray at home, esp if you are a woman). The main issue is kosher food. If you have a kitchen or small camp stove, you can buy fresh food and cook. Or bring instant noodles. And of course you can't travel on friday and if you are on holiday over shabbat, you can't really go sightseeing on saturday. my MIL prefers hostels/Airbnb over hotels for that reason as hostels generally have kitchenettes. But I imagine for stricter orthodox jews, the fact that the kitchen hasn't been kashered may be a big issue. There are chabad houses and kosher hotels that cater to this. Also most major cities (LA, Hong Kong, Singapore, NYC, Paris) have kosher food delivery. I am not strict, and actually I enjoy going to synagogues whenever I am on holiday. I had an amazing time over christmas with the reform synagogue in barcelona (they invited me to eat chinese food with them cos they wanted to be like the New York Jews lol), and I also went to a service in Singapore. The reform synagogue in Jerusalem was also lovely, they invited me and my husband to hold up the scroll (which is a honour) even though it was my first time there.
