What do you want in your life?
I wonder if they "offered you a position" (and you didn't solicit) might not similar positions be available later? At other schools perhaps.
I think you need to look hard at where you want to be in 5 years down the road. Balance what's important: traveling, experiencing, fulfilling the dream. Or working (for what?) for a family a house a yacht etc.
I guess it boils down to what you really want in your life.
