I've had three holidays cancelled (with a fourth about to bite the dust almost certainly). But I've had full refunds for all of them with no hassle and the longest I waited for any of the monies was about eight days. I even received a refund from Premier Inn for an airport hotel I had booked on a "non-refundable" (i.e. cheap) basis. I had written the money off but a few days before I would have travelled I had an -mail offering me either a change to another date/place of my choice or a full refund. All credit to them.
So I have saved a tidy sum on those trips. I've also saved quite a bit over the Christmas period. I would have had a weekend on the coast with some relatives in early December and Mrs NJ and I have lost the opportunity to put on our glad rags on NYE when we go to a dinner dance and spend the night in a decent hotel. We had booked a nice meal in a local restaurant (knowing we would have to leave by 10 or 11pm, depending what inane rules prevailed at the time) but that too has now been knackered. I imagine the restaurant will be too because it only just survived the November lockdown and I imagine it will never open again. It will be the first time in probably 25 years that we will spend NYE at home.
So, loads of money in the bank (which I don't really need); loads of opportunities to enjoy ourselves knocked on the head. Still I have had the added expense of buying extra Vitamin D pills as we shall miss our winter sun break in February so will have to keep taking the tablets.
