I know that for some people, having a really good holiday is factored in to their plans for managing their life.
Some people I worked with, who had small children,would say that they worked hard, earned good money, and their main 'family time' was 1 or 2 seriously good holidays a year.
At the time we retired I knew other, comfortably off couples, who said that they were going to live in a flat, with the idea that they would spend a good part of the year abroad.
For people who have decided that is a huge part of their lives, the absence of 'holiday' is a huge blow. Personally, i didn't organise my life like that, but I have some sympathy for those who do - although of course they are lucky in the current climate to be able to consider it.
I would add that I have 2 young relatives, front-line NHS workers who made the decision to spend this crisis apart from their significant others (and still are). They have both spoken with feeling about the holiday they will enjoy together when they can.
