Interesting thread. I'm from a working-class family. My parents, older sister and myself, never earned as much as the national average wage and I'd guess we were well down in the bottom quarter. As a child, we never went on holidays. I heard a little about it from other children and read about it in books, but really had no idea of what it was like. My grandmother and her second husband, similarly poor, managed to save enough for one week a year at the seaside.
My sister must have had more drive to try holidays and managed to go on a week package trip abroad when she was only 18. Later when her husband abandoned her with two children, she managed to take them away for the occasional camping holiday.
I never saw any point in holidays! I tried to make the best life I could at home, then holiday meant for me, swapping that good life for something less, or at least untested. Drinking, paddling in the sea and lying in the sun were never attractive to me - I don't do that at home, so why pay a lot of money to do it somewhere else?
Later, I did get the chance to go abroad, sometimes to work and sometimes to visit my sister who had emigrated. Such trips were either free (work) or cost me my fare and some contribution to food costs (family.) There was some interest in seeing different parts of the world at first, but gradually everywhere became much like here, especially the seaside and large towns (like where I live.)
After my mortgage was paid off and I retired, I eventually tried "normal" holidays. Just after Christmas (about 12 yrs ago), a friend told me she'd seen a short-notice holiday reduced to £200-a-week all-in in Tunisia. Although she decided never again for Tunisia, we found similar deals in Greece and Spain, progressing over 6 trips to over £300 a week all-in. It's nice to get some warm weather that time of year, but otherwise I can take it or leave it.
Then her relatives moved to Europe, so we did visits (calling them holidays), but they cost more than the off-peak packages (Flights cost more to non-holiday destinations, sometimes they could not provide accommodation and we always contributed to their extravagant food costs.)
So I don't think OP is unreasonable, but I'm amazed that so many people want holidays at all. They must be what I see as rich people, who can afford to buy better accommodation, transport and food, just for a week or two occasionally. Personally, I'd say, spend your money (what you can comfortably afford) improving your life at home and enjoy it all year round.
