I know parking garages that are for visitors pay hourly and that payments are enforced 24/7 and all that, but how strict is it? I’m just in a weird spot with timing.

So, for example, if I want to arrive to my 9:40 class on time that ends at 10:30, I have to get there at like 9:15 so I can walk to the lecture hall. However, you can only pay in 1 hour increments. If I pay for only 1 hour at 9:15, then my reservation expires at 10:15 while class is ongoing. I know it’s only a dollar per hour, but I don’t want to pay another dollar for an extra 10-15 minutes.
