I heard you don't have to fly out. My friend buy bus ticket to Malesia. I don't know it's okay or not but that she did. When I travel before I don't know where I want go next, and fly or boat etc. Lots of backpackers don't know where they go to next and when. I can fly to Thailand but I can also fly my home country after trip example from Vietnam. I think embassy give you right answer.
I have also always. I have being travelling in Thailand 8 years. But now problem is medicines that you can't bring to Thailand. You can find list from RTE page. There is lots of medicines that are allowed in Finland and Europe but not in Thailand.
My husband is Thai. I was surprised that my medicine in Finland is 8 euros and in Thailand it's 100 euros. I have very good insurances. I just put my words wrong. I don't like pay medicines hundreds euros that I get almost free from Finland and I can't bring those with me when I come. But if there is not any changes then I buy medicines from Thailand.
