We've used the standard
DDP about 5-6 times now. Last fall we did the QSDP for the first time. So how did we feel about only getting CS instead of TS and CS?
We FELT GREAT! (and full!)
Personally I didn't have to make all the plans, and ADRs for our Dining. Trying to figure out where we might want to eat on a given day wasn't always that easy.

. I would make at least one ADR per day and then we would usually keep about 1/2 of them and reschedule the other 1/2.
My DM loved the fact the we didn't have to schedule our day around a TS meal.
Now, don't get me wrong, I really enjoyed eating at most of the TS we ate at but not having to do TS (and we didn't do a single one last year) was a nice time saver.
I did miss some of our favorite TS but we also tried a few new CS ones.
Personally, we had plenty of selection. Neither my DM or myself had one burger or chicken strips the entire 10 days. I don't think my DD11 had a single burger either.
If you go with the QSDP I think you'll be happy-we were!
Oh, and now that you can make ADRs so far out there's no way I would get the ADRs I wanted. It was hard enough to do it 90 days out.
BTW, some of our favorite CS places are at DTD. We always have a rental car so getting to DTD or another resort is never an issue!
