Driving the big loop around Lake Superior gives you five hundred miles of rocky shoreline, cold pine forests, and quiet roadside fish shacks. You want to book those lakeside motels by late spring for a late summer trip, because the good spots fill up fast and options get thin.
A typical trip runs about sixteen hundred dollars for gas, food, and lodging. Spreading that cost out over time makes it easier to handle without putting your normal budget in a bind.
Remember that the introductory window is a hard deadline, not free money. If you still have a balance left when those eighteen months are up, regular interest kicks in on what is left over.
