What is different between "travel to" and "travel into"?
"Travel to" refers to traveling towards a general location. "Travel into" refers to traveling towards a location, but the location is specifically an enclosed location. Therefore, because "work" is generally an enclosed building, "into" is used here. Ex: I am traveling to Germany next week. ("To" is used because "Germany" is a general location) Ex: We are traveling into the cave now. ("Into" is used because a "cave" is an enclosed space)
