addiedisney - You are most welcome! The codes often confound many, as everyone finds them curious.
I should have said in my last post the room assigners used to assign rooms 3-4 days prior to your arrival, when your reservation was downloaded to the resort. Even then, no one could get their assignment prior to check in, as it isn't set in stone. If a current guest needs a re-assignment (for instance, don't like view or floor, or a maintenance issue occurs), the guests not yet checked in can be moved to other rooms as necessary.
A year or more ago, WDW switched to a computer system that assigns rooms, and I'm not clear on how it works - but it certainly seems to be very fluid, and rooms can and do get switched around as guests check in.
HTH!
xrobx - Welcome!

Congrats on your first GF stay, and so soon!
As
psac posted, the TPV rooms should not be impacted at all in regards to view. All of these rooms face the CR and MK, although a few end rooms in Big Pine Key may have a panoramic view that includes the Wedding Pavilion, and therefore the construction. I would probably request Sago Cay or Conch Key, as those buildings are furthest from the construction area and are not likely to see the mess.
In regards to noise, most recently returned guests have stated they have not heard anything. I hope this is still the case in March, but there is really no way to tell. Keep following here on this thread, I'm sure there will be reports as the construction progresses to help you.
Disbug1 - Welcome!

I'm not at all familiar with the NYE party, hopefully someone will pop in who can answer your question.
Disney-Kim - I have quite a few room photos, and will be glad to post some after I run a few errands. Is there an angle or room amenity you particularly want to see?
There is a GF photo thread in the photography board. Here is the link, some of them go way back and have been deleted, but you should be able to find a lot of photos:

CoachBagFanatic and
pas130 - I certainly understand the desire to stay elsewhere until all construction has finished. The GF is the most expensive property, and we are debating staying at BC or AKL until everything is completed. On the other hand, most guests are reporting little to no impact, so we may take the chance - we can always move if we find it unacceptable.
