Don't know what kind of consulting you are involved in, but most IT consultants I know go to the same third-rate town for months, if not years on end. Then they move on to the next. Sure, you may see your fair share of domestic towns & cities, but don't expect to see "the world" unless you have some sort of qualification that no one else has.
I am also working as an IT consultants, but I have projects around the world and expand my stays over weekends on the destinations, so that I can combine working and private interests together.
