Depending on the time of your appointment, you could drive to Duluth easily in the evening after rush hour, overnight there, and do the appointment the next day. Hotel availability might be limited (or very expensive) further north during the summer high season.
The drive along the shore is very nice, assuming that you can avoid busy summer weekend migration times. My recollection is that from Duluth to the border is about four hours driving time, not three, even if one only stops briefly once to stretch or get gas. Enjoy!
ADDED: AAA says the drive time is 2:43. YMMV, especially if you hit bad traffic along MN-62. Of course, one potentially saves a lot of time by taking the expressway to Two Harbors or whatever rather than the shore route, but the shore route is fun to do in at least one direction.
