There is no need to book hotels or apartments early as long as there is not high season. Study where you go and you may book early if free cancelation, then you are free to change and get the best deal. Most cases we have bad experience with early bookings and great experience with bookings close up to the visit.
In most cases Google map is a fantastic, and it even selects roads that you never will visit unless google help you finding them. Even in Indonesia it works most of the time. The only problem is that google map does not differ if you drive a normal car, 4wd or motor bike. My advice is: ask the locals when you end up in suspicious places, and you may study the map before starting the drive.
In every passport there is now an area that is machine readable (below the picture of you). Especially for persons with Æ, Ø and Å in their names this is important in order to avoid spending extra money and time. Passport, Visas and flight tickets should be exactly the same!
Using prepaid sim card will nearly always be a good idea when outside Europe. The most effective way is to buy it on the airport – you want get lost and you do not have to spend a lot of time to get it elsewhere.
In Malaysia several larger apartment buildings had a community cantina at ground floor, and I think the people living there had an opportunity to get dinner every day for a small amount of money. And they did not have to spend time, shopping, making the dinner or clean up after. Much like we are doing traveling around this year:) Is this a business idea possible to realise in Norway?
In Sri Lanka we experienced that washing machines, refrigerators, and other large items were sold on tax free at the airport. Never seen that before, an probable never again:)
The holy cow does not have a good life in India, living in cities, on roads and so on. Eating garbage and drinking mud water. Poor cows!
