Taxi from Milwaukee to Wisconsin Dells?

You are talking hundreds of dollars. Figure miles times about 3 dollars a mile. Unless you can work out a flat rate with a driver. You might look in to a bus service like Greyhound, Van Galder out of Janesville Wisconsin, or even a limo service. Call the Dell's Chamber of Commerce and see what they say. Maybe they know something. I used to live in Lake Geneva and owned a taxi service near Chicago. I now own a service in Spokane.
