I did NOT know this! One of the only reasons we book through AAA is for the Diamond Parking Pass!
However, in 2010, we were planning to drive down to EPCOT during 1 day of our beach vacation. If I remember correctly, when I called to ask our AAA agent if we could have a Diamond Parking Pass, she told me that the Diamond Parking Passes came "packaged together" w/ the AAA MYW packages, so we couldn't just have a Diamond Parking Pass - we would have to purchase a package to get the pass.
Yes, if you're staying at a Disney resort, you can park at the parks for free.
However, if you book a package through AAA, you're given a Diamond Parking Pass - which allows you to park right behind the handicapped sections at the park, which is nice because you're always within walking distance to the front gates & don't have to wait for the parking trolleys if you end up at the back of the lot.
That's what I'm thinking about POR - that there are no more AAA discounted rooms.
However, w/o any discounts at POR, it's actually a little cheaper for us to stay at Beach Club w/
free dining or much cheaper for us to stay at FW w/ free dining.
So, DH & I are currently deciding if we'd rather stay at the Beach Club & be a walk away from EPCOT or stay at FW & be a boat ride away from the MK.
