Route from Germany to Tuscany and back ???
We are traveling from Germany (about 2 hours east of Frankfurt) to Sienna. Mapquest has the route going down through Innsbruck to Italy, but the return route has us going through Switzerland. Any idea why it would give a different route for there and back? Just curious.

You mean Grosslittgen WEST of Frankfurt?
The algorithms of route planners and GPS systems do not compare all possible routes to find the best one, but they stop calculating if they have identified an optimal route. The algorithm starts at your starting point and, hence, may lead to different results for the return route.
However, the route via Innsbruck is grossly wrong.
The route via Switzerland is 1133km/10:22 and the route via Innsbruck 1247km/11:01 (according to yahoo.maps which allows to modify the proposed route manually).
Another factor is the toll. The Switzerland route required toll on French autoroutes and a vignette for Switzerland, the Austrian route a vignette for Austria. Some route planners consider this too, but you can change the settings.

In fact, many online route planners do not work well. Mapquest is especially bad.
See this thread:

My experience is that for Europe, www.viamichelin.com produces good results (and offers touristic information and restaurant/hotel recommendations). Otherwise http://maps.yahoo.com/ is a good route planner. Here I like the option to manipulate routes by dragging the line on the screen.

I am fond of www.map24.de which states for your particular route via Switzerland and then Milano.
A4 followed by A 2 via Milano taking the A1 = 1117 kms.
Safe trip!
