I am going to be at the poly in 8 days!!

And now I am starting to get uber excited

and just a leetle, tiny bit panicky/nervous.

So I have a few questions...
1) I made the reservation for the Poly for Dec 9-15 but I never said any preferences when I booked... is it too late now to request a preference over the phone or is it best to just wait until we arrive and ask at the desk when we check in?
2) We are actually arriving in WDW on Dec 8th(afternoon) and staying at the ASMovies for the night. Is it silly of me to try to check into the Poly the day before(the 8th) or should I wait until that following morning when my ressie there begins?
3) This is related to the above question, sort of...I am anxiously awaiting any reports for this early/advanced check in that is being offered for guests of the Poly... seems like it might not be worth it because then you dont' have the advantage of choosing a room if you are given a choice for the day you arrive... thoughts?
4) My preference for a room is close to the GCH...we are doing the Garden view rooms... I read and re-read Tikimans site and this thread, and carefully decided that the best longhouse for us was Rarotonga.
However, I keep hearing and seeing this 3rd floor Samoa view and I think hmmm well maybe I should ask for that. But since I am weird and a neurotic clean freak (thanks mom)...I am afraid to stay in any 3rd floor Samoa room because of the high traffic these rooms are seemingly getting. (aren't I weird??!!) I know that they were refurbished recently but I still have this weird worry that the 3rd floor Samoa rooms will have seen a LOT more traffic than a room in Rarotonga for example. WDYT?
