Which is cheaper?

Is independent travel less expensive than booking guided tours lasting 3 weeks? The answer varies. Organized tours package essential services like accommodations, transport, meals, entrance fees, and activities into a single price, while independent travel involves booking each aspect separately. To assess which is more economical, compare the tour price with what you'd spend arranging everything yourself. If you prioritize budget options or premium experiences, the cost comparison could swing either way. Always review the details of what's included in the tour package to decide.

Also, before booking a tour, make sure you know exactly what is included as tour companies sometimes change their itineraries or included amenities to keep them updated with seasonal changes and customer interests.
