We stayed at the Country Inn & Suites in Middleton for $100/night and it couldn’t have been better. We got downtown early enough on race day to get free street parking. After I finished the swim they went back to the hotel for complimentary breakfast, then headed a few miles west on Rt 14 to catch me on the bike in Cross Plains. After I passed the second time they went downtown and parked at the stadium and took the shuttle in, but they had stopped collecting parking fees for the day, so they parked for free again.
Worked out pretty well for us.
