I'm thinking that a lot of people will upgrade. However, I've heard of some people glad it's the QSDP offered out of convenience of no ADR's. I've even seen some posts where people staying in moderates and up want to downgrade, which is NOT allowed. So, while a lot will upgrade, I think there will be quite a few that don't too.
We are booked on 2 pacakges at Pop - one at each end of our
Disney cruise. I received a Pin for the regular dining plan Free even on the values. On our stay AFTER the cruise, I did opt for the free DDP since MIL will be with us and it will be nice for her to have a break with a TS. However, for our stay BEFORE the cruise, I have opted to book the Visa code of QSDP free even though I could have booked the DDP for free with my Pin. Since it will be just the kids and I then, I want the convenience of no ARDs.
So, my point is, there will be some that like the convenience of no ADRs that they will even pass up the DDP free with a PIN and opt for the visa code/general public code free QSDP. But a fair share will upgrade or use their PIN.
I don't think I was very helpful was I
