Everyone that I know is escaping that island. Why would you put yourself in a situation with bad weather, bad food, bad teeth, high inflation, and Little India everywhere you go? Before my visits, I have to watch 5 seasons of Peaky Binders just to prep myself for that working class English accent.
Listen, when you arrive in Vietnam, just tell the IO that you are running away from the freezing weather in England and they will give you a free 45 day entry.
