I plugged-in the CR for 8-31 to 9-4 for you and there are no CL rooms, but it is $1481 for a Tower/BLV room and $1616 for a Tower/TPV for 3 adults.
The GF is $1886 for a std. (SL) CL room, which I think you and your parents prefer. There is also a RPC/TPV room for $2561.
I had to click-on the details of the offer on the special offers page many times before it would actually go to the booking page. Hope this info. helps

Only the nights that are within the travel dates will be discounted. You must check in during the travel dates listed above, however, your reservation can extend past the end date of October 1, but only the nights during the available periods will be discounted.

At this point, it does not appear that any nights are blacked out. These prices are for the room only, and do not include the 12.5% room tax. Weekend nights may be more expensive that weekday nights. As with all Disney discounts, you can only use one discount on your reservation. Free Dining is also available during many of these dates, and may be a better option for most people.
You are able to add Magic Your Way park passes and any of the Disney Dining plans to these discounted room rates, making the reservation a Magic Your Way package. Neither the park passes or dining plans are discounted. You must add park passes to the reservation on order to book one of the Disney Dining plans.
