Your plan and suggestions are composed using your preferences, visit time, method of travel and the corresponding information about sights: their types, opening times, location, typical visit time and popularity of the sight.
Set your preferences by moving sliders left or right. Moving the slider left will give fewer suggestions in that category, moving right will give you more. You can set more detailed preferences by opening the subcategory list: just click on the category name and the detailed list will open.
After setting your preferences, click the "Look" button: this will build your personalized visit itinerary. If you just want to see the most popular objects of the selected category mix, click the link "Popular objects" below the button.
At the bottom of the page there are several options for defining your visit - start time and date, duration and means of transport.
The question marks after the sliders give a few hints about what might be included in that category.
The four pre-set options at the top of the page simply move several sliders at once to a predefined position.
