Just fly somewhere nice like HCMC for the weekend, not expensive, experience another culture, very inexpensive too. (Unless you don’t like flying) 🤷🏾♀️
If one of you can do a remote work business (not doing any business with Thais/Thai companies) then that might work to apply for DTV but not if you are both retired, or going to be doing business within Thailand ie. Buying a condo to rent out etc
