Of all the times we've gone to WDW, we've never rented a car (except when I was a kid with my family-obviously I didn't pay too much attention back then). We've always relied on WDW transportation, so I know nothing about parking, driving, etc. This time, we are renting a car for a few days to go outside of WDW. I just need to know the simple logistics of it all:
1. I know there is a security gate thing...how does that work?

Do I have to show my room key or something? What if we are going to a resort just for dining and we aren't staying there?
2. How do I get free parking? I am a DVC member, Tables in wonderland holder, and AP holder, all of which (I believe) entitle me to free parking. Do I have to show one of those passes? If so, where, when and to whom?
3. At the resorts, WHERE do I park? For instance, we are staying at AKV-kidani village (woohoo!)

and we're not planning on doing valet, but we want to be SOMEWHAT near our room. At the parks, I assume they sort of direct you where to park, and you just hike it over to the entrance?
4. Since we'll have a car, where is good (i.e. inexpensive) place to get groceries and to get gas prior to dropping the car off?
Sorry for all the questions, but I don't want to be driving around like a "tourist" (even though we totally are). Thanks in advance for ANY advice.
