Don't be afraid to bargain
People at Southeast Asia are used to do this approach and it’s already a part of their daily lives. But most westerners are shocked to find out that this is considered a standard practice in the subregion. For them, it looks like an unfair deal to the vendors, but actually, it's not.
Booking in advance is not necessary
It is probably tiring and stressful to go to different places at the same time and then going back to the hotel you're staying. If you end up in a certain area and fell in love with that place, and you wanted to stay a few nights in there, then it will be more fun to find a place to stay in that specific place. Your schedule can become flexible if you're not booking rooms in advance because you're the one to decide when and where to stay. But sometimes, booking ahead is a good idea if you're visiting a place during a major event, or if you knew you're going to be tired from a long flight, bus or train ride and doesn't have time to wander around.
