probably not. I've no personal experience of it so can't give that answer. I was in UK when I applied last year but don't remember if flight info was required for application. I was doing visas and Thai passes for 2 people at the time so it's all a bit if a blur now😄
sorry thought you were in UK. the Thai Embassy in London does the online evisa, it comes through by email in a couple of days. But I wouldn't be sure if that service would be geoblocked preventing you from applying outside UK. I'm sure others in this group would be able to answer that. Enjoy Da Nang great beach there 😊
We looked at some beautiful houses and found you got more for your money with a house but in the end we went for a condo. Better peace of mind security-wise.
