Anonymous participant I think they are covering their ar5es these days with the new PM. You will be fine as you fit the profile they want in remote workers. I doubt you will have any issues. My pal just applied for 90 Day O there. He showed them investments of over a million quid. Not accepted and he had to move cash into a personal account. They told him Thursday up to 2 weeks for processing. I said same to him. Covering their ar5es with the timeliness. Enjoy your Christmas in Thailand.
London do seem to be getting picky over remaining in the UK during processing. Two posts in here where the person has come to Thailand and had to fly back to UK. Must be many more.
You will be fine. You do not fit the pattern they are looking to stop. Never extend and return to home country between trips quite far apart. Have a great holiday.
The easiest for a year is the DTV for a family. Unless you are putting kids in school and getting guardian visa through them but that will be expensive.
