I have yet to encounter a parking program that offers a good mileage deal for the cost. For the ones that offer miles they usually offer free parking as an alternative which from my experience is always a better deal. For example the common situation i see is 250 miles for 5 days of parking or 1 free day; valuing miles at $0.02 (generous rate) this is worth $5 while I have never seen parking this low at any of these places. I'll stick with taking the miles I get from my card for buying the parking and take my free days when I get them
