Hint - If you are driving from north of WDW, take FL 429 off of the FL Turnpike. Exit 8 puts you at the western entrance with NO hassle and hardly any traffic. Much better than driving to I-4 and all the way through Orlando. Just be careful if you are using a mapping app - it gets a little wonky once you get on property.
I thought I read about this here but couldn't find it through searching.
