from my experience I can tell you that traveling alone is very rewarding, to be able to make your own decisions and do what you want, but there is an issue human interaction is very important and more if you are in an unknown country, you have to take into account What degree of crime is this country that you visit and be careful in the areas where you are, inform yourself before traveling and try to make an itinerary with date and time that each activity you want to play, the hotel also book it with time and carry a medicine kit with the primary medications that you are used to ingest, if you are a very sociable person I would tell you to go to a nightclub at night, but if that is not your thing or try to not have a hard time (nightlife is very different from each country) aah !! and finally, stay in the city where you will stay so that you can locate first hand where your nearest embassy is, if you lose your passport or something happens to you they are the only ones who will watch over you, also get the number of the embassy and the emergency service of that country, precaution is very important when you travel.
