Trying to make this decision myself... We have stayed at both. Comparing the two, I think POP has a better bus service and many of the rooms are closer to the main building where dining and everything else is. The pools are nice, but there are no hot tubs or slides like CSR has. CSR has a really nice main pool. CSR is really spread out though so there is a fair amount of walking depending on where you are staying and the bus has multiple stops. The beds are queen though (POP has doubles, at least the old rooms have doubles). Both have some entertainment (e.g., movies at night) but CSR has a fire pit with marshmallow roasts... There are more dining options at CSR (including a TS) but POP has some nice options too (they have a great yogurt parfait station which is great for breakfast--it is a snack credit)... We found POP more noisy (walls were VERY thin) and the beds were definitely less comfortable compared to CSR. We liked the feel of CSR better. It felt more like a resort. Having said that, our kids definitely thought the large iconic figures all over POP were very cool. It is a hard one... We are going for 14 nights and for us it is a difference of about $1,000 USD (around $1,370 Canadian). I am definitely leaning towards POP if the moderates are offering free QS....
