I’m planning a trip around the world and I’m wondering how many days it would take. I’m looking for the most efficient way to do this, so I’m not looking for a leisurely trip. I’m hoping to get an idea of how long it would take to visit all the places I want to see and experience. I’m looking for advice from people who have already done this or have knowledge of how long this type of trip would take. Any advice would be greatly appreciated.
