The parking is included in the resort fee, which is bundled into the cost. You get a pass at check in for the self parking and you just display it on the dash board. In and out is very easy, often there is no one checking anything. Just be sure to leave the pass on your dash and no worries.
You DO pay a daily rate, it's in the resort fee. For the GCH it was $10.50 per day, for PP it was $9.50 a day, I don't know what the DLH is but there is a fee. They also charge for valet parking.
