Do you live in Milwaukee? Or will you be staying in a hotel? Take her to Kopps and let her get whatever she wants, even if there's no chance she can finish a 4 scoop sundae. Get a hotel with a big pool, and let her swim for an afternoon. Discovery World is a blast, and the Zoo never gets old to a 6 year old. I haven't lived near Milwaukee for awhile, so I don't recall all of the places. A salon is a great idea! Let her get her hair done, toes and fingers painted, and then take her somewhere special for dinner. The nice thing about that age, is that special to her, does not necessarily equate expensive or fancy. Get her a makeover, maybe let her get a new outfit, then take her to dinner and a movie perhaps. Does Milwaukee have one of those "classic" theatres? That might be cool. From my experience, my daughter wasn't that big on sight seeing at that age. I tried taking her on trips that I thought sounded fun, and she was bored. My best luck came from doing normal things slightly different. When we went out as a family, we didn't order dessert. On Daddy/Daughter trips, she got dessert. Little stuff like that seemed to make the difference at that age.
