When checking into the Poly, do you have to use Valet parking? Our family of 5 is driving to WDW and we plan on parking the car and not touching it for a week. If you don't valet park, do you still get the cart ride to your room? With 3 kids we travel with alot of stuff. What if it doesn't fit in the cart - can you bring the rest to the room yourself? I know these seem like silly questions but we have never stayed here and I need to know how to direct my family once we get there.
