When is your trip? Is it during a time you know for certain you will be able to swim? Realize, BWI's main pool is not in the Inn, it's over in the Villa. While not as far as Kidani's pool, it's not right there.
If you don't have a pool view room you aren't likely to hear any noise
Otherwise, BWI is my favorite resort, even though AK is my favorite park. I enjoy AKL a whole lot too. And I wouldn't let their current construction plans stop me from staying there, especially if it saves me money.
And while BWI is my favorite, I do recognize why folks find the set up of the lay out a bit off putting. Especially if you have a kid in a stroller. You are left to use 2 elevators every single time you want to go to the Boardwalk proper, which means the Bakery or to HS or Epcot.
And the Bus to AK and DS will share with other resorts, often all of them, which I do find annoying and I often use to do Uber to AK instead of using the Bus.
So you'll have some trade offs if you pick BWI over AKL, you'll be trading construction for a couple different inconveniences. You'll need to see which would bother you more.
