We stayed at the Marriott Residence Inn Louisville Airport for Master's Worlds last January and are staying there again this year.
The management has approved preferential pricing for anyone wanting to stay there during the racing in January/February 2013.
Marriott Residence Inn Louisville Airport is an easy 15 min drive from the race venues. They have lots of parking as well as free airport shuttles. Their suites have fully equipped kitchens, have queen size beds in the bedrooms, plus a sofabed in the living room. They offer free hot breakfast every morning and happy hour (free beer/wine and light meal) Tues-Thurs evenings.
2BR suites are $119 for us, which is a $60 discount off retail. 1BR or Studios are $99/night.
There are 4 2BR suites available currently, we're booking two for sure. Lots of studio/1BR suites.
Can contact the hotel directly and book under the 'cyclocross' rate.
