Going on your own is fun, but not safe. You will not be backed by a travel agency, all costs will have to be borne only by yourself. In addition, it is important to understand correctly where you are going and why. It is more optimal to entrust a seaside vacation in Turkey to a company, but a trip to Europe will be more exciting if you organize it yourself. In the latter case, in order for the rest to bring only the most pleasant moments, exclude in advance the possibility of mistakes when planning your trip.
The most important thing in independent travel is time. You need to understand that in a territory located in a different time zone, it will be different from yours. Fly to the West - subtract, to the East - add.
A common mistake when traveling on your own is choosing the wrong two flights if you are not transferring to connecting planes. When booking, carefully check the arrival and departure times and be sure to discount the delay (at least 2 hours). It is better to spend extra time at the airport, exploring the shops, than to lose a rather large sum due to a late plane.
Calculate travel costs carefully. Being overly relaxed is the traveller's mistake. Like, I paid for the tickets - and everything is in order. But it was not there! Remember: travel alone does not include a shareware transfer. You will have to catch a taxi, take a bus or a ride and pay extra on the spot. Always have a certain amount in your pocket for such expenses. It is better to find out the approximate rates in advance on the thematic sites.
The mistake of an independent tourist-novice can be a lack of awareness of the possibilities of the area. As a result, you will be doomed to sit in one place for the whole vacation without seeing the most interesting nooks and crannies of the area. Be sure to purchase a guidebook and plan fascinating routes from home in advance. Remember that no one will offer you excursions, so try to arrange everything possible before departure (for example, you can purchase excursions to Disneyland, Versailles or the Vatican through the official websites).
Fear of the locals is also one of the common mistakes. In no case do not be ashamed of your "spoken" English and feel free to ask for directions or working hours (for example, referring to a phrasebook). As a last resort, you will switch to sign language. But in no country will you be "sent away" just because they did not understand. Be brave and you will learn a lot of interesting things about yourself and the host country!
