How much preparation time should be planned for planning the trip?

Everything depends on the duration and complexity of your trip. For a simple route, a quick exchange via e-mail is sufficient. But if you are experienced and discerning traveler, you can spend several weeks in contact with the agency to plan your ideal tour. In any case, take enough time not to depend on booking capacities and higher-priced general travel times, as these can be limited during the high season.
