I hate to add any doubt into otherwise wonderful feelings, but I'd feel bad if I didn't share my opinion here.
Personally, I'd be very dissatisfied with a TPV room in Aotearoa, especially a 2nd floor room, since these don't have balconies. Aotearoa is set back pretty far from the lagoon. At Poly, TPV is defined as an unobstructed view of Cinderella Castle. From Aotearoa (or at least from standing right in front it), you have what I'll describe as a "tunnel vision" view of the Castle, due to Fiji and Tuvalu on the right and the Luau Cove on the left. And like I said, there is a lot of land in between the building and the lagoon. AND, the path in front of the building is the only path, or at least the main path, between the bulk of the resort and the Luau Cove, meaning the crowds of people going to and from the Luau have to pass across the front of the building, on the path that is direectly in front of and adjacent to the building. I would imagine that gets noisy a few times a day, and would also take away from privacy, especially (I'd imagine) for the first floor rooms.
I think Tuvalu looks like an excellent location, but keep in mind that the 2nd floor rooms have no balconies. There's also no beach in front of it ... it's just about right on the lagoon. This wouldn't be a problem for me, but might be for some people.
I requested Tahiti, 3rd floor (I just figured the higher the room the better the view of MK). I picked Tahiti over Tuvalu because, if for no other reason, both the 2nd and 3rd floors of Tahiti have balconies. It's also very close to the TTC, which I prefer.
I'll put it to you this way, to illustrate how strong my preference was. We arrived to check-in at 9:45 a.m. We were assigned a 2nd floor room in Aotearoa,
and it was ready for us. I nicely asked the front desk CM if we could get our request, a 3rd floor room in Tahiti. She got on the phone, and then told me we could have our request, but would have to wait until mid-afternoon. As it turns out, our room wasn't ready 'til 5:15 p.m. As unhappy as I was to have to wait that long, I was thrilled that our request could be met, and waiting until after 5 was a small price to pay for 8 days in a room I strongly preferred.
Just my 2 cents. When I think that I could have paid the same amount of money and had to keep the 2nd floor room in Aotearoa, I consider myself very lucky that they were able to accomodate my request. Just my opinion.
