We've enjoyed long stays at both resorts.
AKL is gorgeous. We loved everything about it from the restaurants to the art & architectual details to the landscaping. However, the very best part was having a view of the animals from our own balcony. I wouldn't stay there without a savannah view. It was certainly a splurge for us, but well worth it. Our October trip was our most relaxing trip to WDW yet.
POFQ has its good points too. We really like the resort's convenient location and the boat to DTD. It's a well-themed, compact resort, which I find to be quite romantic as well. Although the dragon pool would be really fun for kids, too! For a more budget-minded trip, this is our choice of moderates.
Really, it's a matter of budget and theme. If you can absorb the extra $1000 pretty easily & the African lodge feel appeals to you, then I'd definitely stay at AKL. Just don't skimp on the view. Be sure to book reservations at Jiko & Boma, too!
