Hi! We just got back from POFQ (Feb 4-11) and absolutely loved it! The transportation was great because the FQ is first on (before POR) and first off. It never took an excessive amount of time to get to the parks.
My DDs (just turned 4 & 7) loved the pool ... they have a nice-sized water slide (not too big) and a kiddie pool. They also have a ton of different sized life jackets. My DD4 used one and could paddle all around in the 4 feet forever. They also have a nice playground right in the middle of the resort. Everything is close because the resort is so small. The food court has a tv (always playing disney channel

and a coloring area with small tables for the kids. They were also giving out Mardi Gras beads to the girls everytime we went for breakfast (great Mickey Mouse Waffles!)
As for the parks ... my DD (just turned 4) loved the characters! She had the best time with her autograph book. I bought small, blank, spiral scapbooks and let them decorate them with stickers on the plane. She really loved all of the parades too.
Rides ... she really didn't like the darker rides (inside) even pooh bear and peter pan. She loved Dumbo, Barnstormer, Small World, Magic Carpets, Triceratops Spin etc. She loved the fountains at Epcot (the main one & the jumping ones by the Imagination Pav). You just have to take it at their pace ... def bring or
rent a stroller! This will help immensely!
Let me know if you have any questions! Happy to help! Have fun!
