did you pay for your ASQ in Phuket? Without the direct flights to Phuket, you may face problems. I know people who have crossed land border from Cambodia and were able to arrange a car to take them from the border to their ASQ in Bangkok, but it was expensive. You may be able to arrange something from bkk to Phuket (although unlikely).
Thais still need to eat. So if it’s a restaurant aimed at the Thai market, that could work. Maybe leave it a while to see what happens with the current Covid situation.
I was born Naples (Bacoli) so, I understand that calling of the sea. Yes, Patong is a ghost town. But I was actually referring to all Phuket. I like to do all the adventurous activities as well but, I also like to eat a meal at a nice restaurant or, stay in a nice hotel. Many have shut up shop and are waiting for the return of the Farang. Just be aware of that, ok.
When was the last time you visited Phuket? Since this whole Covid malarkey began, it’s not at all what you remember it as. The only area that’s tolerable, is Phuket town.... Everywhere else is a ghost town!
right now you should be opening a business that targets Thai clientele. Anything aimed at foreigners or tourists, is going to take a long time to get going.
