We usually go away in the UK with our grandchildren for a week in the summer holidays. My husband and I haven't been abroad for about three years and I was rather hoping to do so this year as we have had a pretty terrible year with two close bereavements. But I have been unable to book self catering accommodation anywhere, even at the very expensive end of the market. Virtually everything is booked up. I think we will just have to make do with days out.
My husband's family is abroad and I don't think it's unreasonable for people to feel upset that they won't be able to see their families for the foreseeable future.
Of course, people don't "need" lots of things - TV, cinema, theatre, pubs, restaurants, etc, etc., and to some extent it is good not to rely too much on external entertainment and facilities. However, while I enjoy going for long walks with my dog in the forest during the summer, I find it tedious being stuck at home through the winter months. And UK holidays are great if you get at least a few days of good weather, but if you are unlucky enough to have a week of virtually solid rain it can be very disappointing.
