To plan a travel itinerary, create an outline of your desired destinations, arrange them geographically to avoid long trips across locations, and write travel ideas and possible accommodation choices in notation. After setting concrete travel plans, book flights and hotels in advance. Determine the activities you want to enjoy at particular locations, especially the attractions you want to visit.
When listing down the places you intend to visit, group nearby areas together to save time and minimize traveling costs. If you plan to visit Europe, use a European rail timetable, and identify several trains running between cities. Moreover, find out about available hotels and accommodation options in each city by reading travel guides or checking travel websites.
Book a round trip ticket if you plan to travel abroad. Also, if you anticipate the expiration of your visa while traveling to a certain country, book a train to a nearby country to avoid penalty fees. When planning local activities to do in varying locations, include the amount of time you need for each activity.
An itinerary is not a definitive plan, and you may tweak it depending on your changing plans. This document basically gives you clear ideas of the places you want to see, the time you depart and arrive, the means of transportation to reach your destinations, and your lodging options while traveling.
