Tourists seek escape form the corporate world. They do not seek perminant escape- they only seek a break so they can return to the grind refreshed. Travelers are similar except that the time scale is longer. Very often travelers are engaged on a 'gap year' between university and work. The aim is to build a bank of memories so that work and middle age seem barable- and life seems worthwhile.
The third type is the pilgrim- one who seeks answers to specific questions. I am a pilgrim.
Travel is the best philosophy teacher.
