So FI and I are not going to go on a honeymoon right away, but we are going to take a couple days off and "runaway".  We were thinking of possibly going to Duluth, but I thought I would ask on here and see if anyone has any suggestions.  Places to stay, other places besides Duluth, things to do etc.  We are getting married in September if that helps.  And we don't want more than a 3.5-4 hour drive.  TIA!
