Just to add... It previouslly was only that the first day was free, if you are a resident of the city or county, but I don't remember exactly but probably for those who reside in the city of Boulder or if your car is registered within the city limits, if not you have to pay the first day also. Now this could be dated information but it wasn't that long ago that I parked there. Other than that though to answer your question I don't know that there is any limit as Long as You are paid. I'm sure if you dessert your car there or abandon it they will take notice and tow it but if you are paid up I know people who have parked there for a month or two without any problems. And I've known people who were stranded out of town and they just called the number on their receipt and explain that they were parked there and RTD seemed very understanding
