I stayed at this hotel quite a bit last year. It is definitely a 24 hour notice for cancellation.
This cancelation approach is being pushed hard in California (Bay area in particular) lots of FTers are caught off guard by it or the prepaid rates.
Mgmt told me to call them direct if I had to make any changes in my reservation, cancellation etc and they would take care of me. Its a nice hotel, very accessible and as is typical for Towneplace, no breakfast.
