Lucky you--something in the near future to look forward to.
We stayed in Tokelau--really enjoyed it. We were room 3415 (I think), garden view, last room closest to the marina. From our balcony, we could see the volcano pool to our left and the GCH, and of course the marina and Tonga. We have only stayed in the Hawaii longhouse before, so I didn't make any requests just to see where we ended up, and were quite pleased.
We used all of the forms of transport and walked to the TTC for the Epcot monorail. No complaints. The ease of transportation is one of the reasons we love the Poly. The grounds are another reason. We've stayed there quite often, so it really feels like coming home.
We ate at Kona for dinner and breakfast and Capt. Cook's. I liked the ease of ordering at CC's with the new touch screens, but the traffic flow wasn't great. You will be there at a much quieter time, so it probably won't be a problem.
The arcade has been moved to the GCH, so it was closer for us this stay. I never ventured in, but my kids did. There did appear to be more games available.
Housekeeping was fine. I will rarely say it's great. These are my own issues--not necessarily housekeeping's.
Both pools were great. It wasn't hot while we were there, but we did swim just about each day. The quiet pool was much warmer. Again, probably not an issue for you and the time you will be there. We came home yesterday to snow and lightning

so the sun and temps above 65 made us feel quite tropical.
That's all I can think of for now. Anything else, just ask!
