Here's my issue. I own DVC at both BWV and BLT. I have watched cars drive into the BLT lot, park, and the people get out and walk to MK. I've watched empty front row spaces at BW fill up at dinner time.....then empty out about 15 mins after IllumiNations ends. It would be nice if Disney had resort parking lots that are keyed entry. With a particular area for 'day guests'....if they stay longer than a set time, they have to pay for that parking.
I just don't think the resorts that don't have immediate park access have a parking problem. Most of the moderate and value resorts have plenty of available parking.....especially if non-resort people take spaces that aren't up front. Those spots should be left for those paying to stay at the resort....just common courtesy.
