I guess, It has a lot of advantages,For ,example Im a Philippine passport holder.The big advantage for us is that we can travel to 33 countries without visiting,just to have a complete document required,for example plane ticket hotel booking and bank account some other requirements are needed,my opinion as a traveller I can go to other places and see how their country revolve to this modern era,their culture and way of leaving,taste the different kinds of dishes eat some fruits that are rare in our place,hear the different languages of the locals and watch some theatre interpreting their past cultures and if ever i got luck maybe i can attend special occasion most of them celebrate at street using different banner's and having a parade.
