How far away from home do you send your Sims?

I also have what I consider clusters of worlds that in my view are near enough to travel back and forth with ease. (E.g., Willow Creek, Newcrest, and Magnolia Promenade.) I also have a general idea in my mind of what I think the map looks like over all, which includes some worlds that might be in between two different clusters. (E.g., Newcrest, Brindleton Bay, and Glimmerbrook might not be particularly near each other, but they all might be relatively near Granite Falls.) Basically, my sims can go anywhere, but if it's a quick trip to the bar after work, or a shopping errand, I keep them in the worlds that are close to home. If they need or want to do something in a more distant world, it's at least a full day's trip, reserved for weekends or days off, if not longer. Even then, I feel like most of my sims can make it to San Myshuno on a day off; Sulani or Mt. K or Selvadorada usually require at least a long weekend.

That being said, spellcasters can go wherever they want whenever they want, because, magic. I think once or twice I've also had wealthy sims whisk someone off for a romantic dinner far away... you know, in their private jet, as one does.
