since don't know what you are talking about.
BCV has tons of parking - I have never yet seem that self parking close to BCV full. Besides the security guard here wants to know your reservation number for dinner before he lets you in.
BWV parking - I think the security guard makes very plain that any non-resort parking is in the other self parking lot - not at BWV. Now they really, really need to start towing these cars. they can park in the self parking across the street they don't need to park in the BWV & BWI parking lot. But this is a BW management problem not one of WDW or
DVC resorts in general.
Now I have found that several CM park in the self parking across the street. It is them that is your problem. they have their own parking lot that they should be using. but use the self parking instead.
CR security is better. they have to be.
all wdw and DVC has thiefs - look at the latest one at SSR. Now that is an easy access resort. So is OKW for that matter.
just walk over to them - steal what you want and walk back to DD.
