I am planning to do the same..and have booked 3.5 months so far inclusive of ASQ..but taken out insurance for 12 months..and have flexibility with the return flights..The rest will be sorted out in country because there are unknown address changes at moment
If you think it's rough, spare a thought for the staff who put themselves on the line, si rhat you can enjoy what the beautiful country of Thailand has to offer...🇹ðŸ‡
