Hi! I never stayed at Pop, but did at FQ in 2013 when my girls were 4 and 6.
We used a double stroller, I was 7.5 months pregnant, and it was July. We loved it!
Most mornings, we had cereal in the room with Mickey Mouse Clubhouse on the TV, then went to the parks and visited the food court on the way back to our room. I know you pan to drive, but, just so you know, we found the busses easy to use, although sometimes there weren’t places for us all to sit, but we would stand. I did stand for several rides. People usually volunteered their seats since I was pregnant, but I usually declined and was fine.
We stayed for 7-10 days and used 5-7 park days. It was GREAT! My little girls loved the waking paths, the room, and the pool with the water slide.
Of course, I’ve never tried Pop or the Skyliner and a lot has changed at Disney since then.
I have 2 rooms at POFQ booked right now for a trip next month, but it’s short. I’m deciding whether to change to a deluxe or not for the Extended Hours, but I actually think I’d prefer POFQ over most other options.
Good luck, and I hope you and your family have a wonderful time!
