I've seen that as well, and assumed they were marking cars for towing after three hours with no CR Guest parking card.
I didn't mean to be glib with spur of the momenters and resort hoppers will need to find other transportation. But the solution as it stands now does not seem to work well. We stayed at the Poly once with a car and had to troll for forty minutes for a space at the Poly! That is unacceptable - far less acceptable than me deciding I'd like to go to Kona on no notice and having to walk or ride from the TTC (loyal Disney customer and fellow DVCer). And us BWV guests have had the same problem. And I'd prefer Disney not clutter up the architecture with parking ramps. So that leaves them with limited parking and some need to make sure its fairly distributed. I don't think the three hour pass works - for two reasons - 1) its plenty of time to visit the parks from the monorail resorts so it doesn't accomplish what its suppose to do (especially if you are "just" stopping for the morning, or Wishes and Spectro, or MNSSHP) and 2) PSs can take three hours - V&As can, put your kids on the Pirate Cruise and you can spend three hours at the GF (with early arrival and post cruise kid potty breaks), we spent that long at Ohana when they seated us 40 minutes late. The options then become - make it a really expensive pay lot but validate ($15 to park, waived if you spend more than $25 at that resort or are a guest of that resort) or use a guest list.
