I will decide on Sept 17, depending on what the news is like, that gives me 3 weeks to sort the COE paperwork etc, for whichever destination I end up visiting (which may well be Spain!)
Key requirements for me would be removal of the curfew and the reopening of open fronted beer bars (at a minimum)
My main fear in delaying a Thai trip till January is that by that stage Europe might be back into a lockdown as the covid shitshow starts all over again
