There is not room to park 2, unless you are excellent drivers. LOL! I only say this, because if you are on the grass at all (very narrow), they will give you a notice and if they have to give you more than one, they will visit in person to have you move your car. The official stance is that it fits just one car and that will be 19.00 a night and the 2nd car will cost you an additional fee. We were just there in March with 2 cars and needed to keep one up front (No biggie as we didn't use it all) but when we were unloading and inside for at least 20 minutes we came out to the notification. LOL! Oh and your golf cart (if you have one) has to be in the driveway as well, not parked on the 'grass' so make sure there is room for that.
You will have to park the extra car at the front desk lot, near overflow. This will be difficult in light of the holidays, so once you find a spot, don't move it and plan on just using the other car the rest of the time.
We are headed there again in October and this time will only have 1 car this time but needed to inquire about the overflow lot since we swap between cabins and our RV a few times during our stay and they told us that their parking lots and overflow lot will be very full most of the time.
