The first step to design the itinerary is to understand your travel style. You need to tell me:
* Where do you want to go and for how long
* What is your travel style (budget, adventure, stylish hotels)
* What is your budget
* What should be the focus of the trip: cultural, activities, people, general
* Specific sites you want to see and specific activities you want to perform (if you do not know I will suggest)
