Which is cheaper?

Is traveling independently less expensive than taking guided tours lasting 3 weeks? The answer isn't straightforward. Guided tours often include services like hotels, transportation, meals, entry tickets, guides, and activities, all of which you would need to arrange and pay for individually if traveling on your own. To determine the cost difference, you'd need to compare the total cost of the tour package with the cost of booking everything separately. You may prefer a less expensive hotel or splurge on dining, so the cost of a tour could either save you money or cost you more. Be sure to review what's included in the tour package before making your comparison.

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.
