There is a map of Disney property. Print it and keep it in your car!
You can go as the previous posters said but that's the long way through lots of lights and traffic and makes you cross through pretty much all of Disney property.
I go all the time and I use the backroads...MUCH faster and less circling all around.
Just go north on Buena Vista Drive.
Then Vista Drive (connects by about 50 feet of Live Oak Lane).
Then that turns into Vista Blvd. but you are still staying on the same road.
You will pass the Ft. Wilderness campground (not lodge) on your right.
At the next stop sign intersection turn right (you will bypass the toll plaza and won't have to worry about crossing over traffic there).
Follow the signs to Wilderness Lodge just about 2 blocks up (It will be a right turn at the light).
I use these backroads all the time...it's super easy.
I was there 5 times this past year (over 40 times total and 3 times in just the last 2 months and I always have my car and drive everywhere.)
Just keep the map with you in the car no matter which direction you take.
Oh, and at the security entrance at any Disney resort, you will have to show photo ID.
(We just ate at Artist Point last week....portobello soup..YUM. They don't have the side dish of french fries fried in truffle oil anymore, but if you ask them, they will make it for you ($6). It goes awesome with the soup.) All of their homemade pastas are great too...as well as the salmon. The buffalo is ok depending on what cut you get.
We really enjoy this restaurant though and the resort. So, good choice.
