[WEDINDISNEY]

1. Where are you planning renting the car from? All the times that we rented we did it from Orlando Airport and went with Dollar rental.
In ref to the gate Im assuming that you mean the one at your resort. You have 2 options, you can show your room key and sometimes ID to the CM guard or you can use your room key in the machine and it raises the gate for you etc.
2. With reguards to parking, since you are staying on property when you check in you will be given a parking pass and just put that on your dashboard and you are good go. When you are going to other resorts either for dinner, to look around etc you will have to go to the security gate with the CM and just tell them why you are there, sometimes they will just let you use the resort parking pass that you have or they will give you a guest parking pass. it depends on the resort and/or CM security. At the parks they have parking CM there that will point you were to park and then you can walk to the main entrance of the park that you are at or you can take the tram and they will drive you to the main entrance.
3. With reguards to the parking at kidani village I havent stayed there yet so I dont know how the parking works if it close to the buildings or if its going to be like AKL where its an open parking spot and walk across to the main house. (Sorry)
4. When we go shopping for our food/supplies we usually go to Walmart which is close to SSR (about a 10 mon drive) or we go to Goodings which is on CR 535 near I4 right near DTD

I hope this helps ya out... No worries Disney is very easy to get around and you will learn things very quickly... :O) OoO
