I have not stayed at POFQ and I see they have opened a new splash area, but 2yrs ago we reluctantly stayed at CBR preferred for FD and were pleasantly surprised (we even stayed in a nonrefurbished room).
The resort is huge and walks to the main building can be far but the scenery is georgeous. Food court was very good no complaints. We loved the beach theme, sandy areas for DS to play (kids meals come in a sand pale with shovel) while we relaxed in the hammock watching some of the higher fireworks.
I don't know how much swimming you plan to do, but the pool is amazing. Zero entry as well as a gated splash area. Your littles will love it. We couldn't get ours out of there. We were even considering there again for this year JUST for the pool for DS (5).
It depends on what you want but I think the FD is worth it. We did so many character meals it was more than worth it!
There is a CBR thread that is so helpful and I also watched a lot of
YouTube videos to get a "feel" of the resort. There are even some where people walk the grounds so you have an idea of how long it takes to get places.
Sorry for the long post, but I hope it helps you out. Good luck!
