We got the All American. Cold fried chicken is a stable at southern picnics, and I thought this was above average, and I stopped eating fried chicken a while ago but would totally order this again.
The coleslaw and potato salad had unique and complimentary flavors to the sweet chicken.
The apple pie was average, but better than most amusement park food, which is what I expect from Disney.
With an AP discount the meal is $12.99, and I believe its $14.99 full price but I know some have reported paying $13.99. I think this is a good deal since it comes with a $3 bottled drink and was being served in reusable bags which combined could cost your $1-$3. So you are getting a better than average them park meal including a drink and dessert for $11.99, trying doing that in most other places in the park!!!
Here is a link to all sorts of WOC dinning info and about half way down is a link to the calendar to order the picnics (but you have to "sign-in" first to view).

As some have said, you can order them 30 days out for the first show. You can get them day of for the second show. And it is my recollection that after Labor Day there will only be one show so they could cancel the picnic all together, but I would love to see them continue!!
BTW, we also did the dinning option at Ariel's. I perfered the seats for the picnic (I wanted the wet zone.) Plus since I wasn't tied to a table and waiting for my waiter/waitress to bring fast passes I could make sure I got there ASAP to get my seat. (Although the food at Ariel's was delicious, my priority is the show at this point!!_
