I know a lot of people love the idea of split stays but it's just too much work to me! The only way I'd consider is if I decided I really wanted to check out a deluxe but couldn't afford a full stay there. Then I might do it for a couple nights, just to see. Honestly, I like to unpack, set up, and be good until it's time to go home. Having to pack up everything and move part way through just doesn't sound like fun.
If you choose either POFQ or POR, they're considered sister resorts and you can use all the amenities at either. It's a short walk along the river between the two resorts (or even a boat ride if you'd rather). So you can go check out the pools at either, have a meal in the food court, enjoy the entertainment or kids activities, etc., etc. Other than sleeping in the rooms, you'll actually be able to enjoy both resorts and get a real feel for each. That would be my vote!
