Thank you both for the input! Just curious, how is staying at OKW. Is it really important to have a car? We would be a group of 7 adults and 4 small children so if a car is a necessity then we would have to get a couple minivans or something similar. How are the GVs at OKW? We've never stayed in a GV before.
They're really great.
Our first
DVC experience was in a Grand Villa at Old Key West that my sister got for our combined families, and it was a really great trip. They're very roomy and comfortable. It feels like a very nice apartment. Heck, it
is a very nice apartment.
We had rental cars and also used the buses sometimes. The bus service is good, but not fantastic. There are three bus stops around the resort plus the main Hospitality House, so it takes some time for the bus to make its way around and finally head to the park. Similarly, on the way back you may stop at several different other stops before getting to yours. When we were there the buses were not shared with any other resort, and I think that's pretty standard.
You can walk to Downtown Disney and Saratoga Springs via the golf course walkway. It's not at all obvious how to get on that walkway, but there's a real entrance that doesn't involve using a machete on the shrubberies down in the southeast corner of the map. You can also take a boat to Downtown Disney, but I gather it's a long ride.
If you mainly just want to get to and from the parks, I think the bus service is perfectly adequate. We wanted to go to some other resorts for meals, so for that we tended to use our cars. And honestly, it's faster to drive in almost every case except for Magic Kingdom, because of the closer bus drop-off there. And even then, if you walk out to the bus stop in the morning and see a bus to MK just pulling away, I tend to think turning around and heading for the car is likely to get you there faster than waiting for the next one.
So yes, if I was staying there I'd get a couple cars. In fact, we're staying this Christmas in a Saratoga Grand Villa with a group about the same size and we're getting two cars (one minivan and one standard). But we're going to a bunch of resorts for meals, and that's where it really helps a lot.
If you're going to be driving around the World a bunch and you have a Garmin or TomTom GPS, I recommend downloading the GPS POI files that I created for MouseSavers. There are some useful shortcuts from OKW to the rest of WDW that both GPSes seem to use, and it's also handy for getting to the supermarket and drugstore to stock up and so forth.

Hope that helps!
