Later this year, I intend to spend 2-3 months in Europe, then want to go to Capetown, South Africa to visit a friend there. Keeping costs down is important. Travel time is not--in fact, a longer travel time could actually be enjoyable (assuming there are things to see along the way)!
My order of priorities when selecting a travel method (or methods) would be:
- Safety I'm not interested in hitch-hiking through a war zone, for instance.
- Cost The cheaper the better
- Scenery/travel experience Flying would probably be the least attractive option by this criteria
I will not have a vehicle, but that doesn't mean renting a vehicle would be out of the question--assuming a rental can be driven through the requisite countries.
As I must eat the same quantity of food, and sleep the same number of hours whether I am traveling or not, I do not consider normal food or lodging expenses part of the travel expense unless they are more costly than they would be while staying in another city.
If I were to travel by train, for instance, where my only option for food was over-priced diner car food, I would consider that a relevant travel expense.
