Brits do like their Summer beach holidays in the sun, and this is witnessed by Spain having regularly been the UK's favourite destination; as can be seen by this typically quiet beach scene, above.
Second on the list of favourite destinations is France.
Like Elephants, Brits have good memories, and I'm sure that many will not return to either Spain or France for quite some while. They will not forget the post-Brexit attitude of these countries towards Britain, and will probably prefer to spend their hard-earned holiday £'s in more friendly countries.
The UK used to send, on average, 18 Million tourists to Spain each year, and 12 Million to France; that's more than any other country, and it represented a lot of holiday dosh.
Croatia, Turkey, Morocco, Bulgaria, and Tunisia are all excellent alternative non-EU holiday destinations (and much cheaper), and, I hope, will benefit from certain nations antagonism towards Britain. Why visit a country where the President/Prime Minister spreads hatred about you, when you can easily go somewhere else where you're welcome? Even Saudi is tempting tourists away from mainland Europe. Pedro, and Emmanuel may come to regret their bad behaviour; especially now when tourist Euros would be extremely welcome.
For the moment both Spain and France are verboten as holiday destinations, and I suspect that Boris may keep it that way for a while (at least until the holiday season is over). My advice is to go somewhere a bit different for a change. You might even find a quiet beach.
