Wow, I didnt know this, Thought you can always visit any resort
Back when we were newer DVC members, DVC members were allowed to park at any other DVC resort. Issues arose when droves of DVCers staying at SSR, OKW and AKL wanted to park at BLT to walk to MK and at BWV and BCV to walk thru the back entrance of Epcot. Now it is no longer the policy. However, if it isn't busy (food & Wine, Flower & Garden, holidays), you
may be allowed to park, depending on what may be going on at the resort (wedding, big convention, etc.).
I've been having some correspondence with DVC regarding a number of things, and I am going to bring up the issue of DVC resort parking. I think it would be great to have some kind of "exchange" parking program between the DVC resorts that are considered "theme park resorts".
For example, DVCers staying on their own points at BWV should be able to park at BLT...and BLT should be able to park at BWV. BCV should be able to exchange with VGF...and Poly at BWV....well, you get the idea. Depending on the number of rooms at each resort and how large the parking lot is.
I see people mention all the time that they never have a problem entering SSR or AKL....and that is mainly because they are not adjacent to a theme park. Although I do know about the annoyance of people parking at DTD and then walking over to the end of SSR to get a bus to a theme park in order to not pay for parking or not go thru the trauma of parking at MK.
