I'd like to offer a different perspective if I may. We actually just returned from a BCV/AKL stay on Sunday.
We've done the extra resort days both ways now and prefer the short resort stay at the end of our vacation rather than the beginning. Here's why.
1. If you're flying and using a towncar service for a grocery stop like we usually do, going straight to a regular room you don't have anywhere to keep your perishables unless you buy a cooler and keep it iced down or pay to have a refrigerator. It was nice to be able to arrive and put away the groceries in the BCV kitchen and fridge. By the end of our 5 night stay, we'd consumed our perishables and only had a bag of chips to move. So much easier than the last trip where we had the hassle with the cooler and then moving all our groceries over to the
DVC unit.
Of course, if you have a car and can go to the store after checking into the DVC unit this wouldn't be an issue, but I still think it would be a hassle to grocery shop after I was already in vacation/touring mode.
2. The two trips that I stayed at a resort the first part of the trip I spent those two days anxious to get to my DVC unit. I just couldn't wait to get there. This time, after 5 days of cooking breakfasts/lunches, making beds and doing laundry, I was ready for housekeeping service and no cooking.

It was like a mini vacation from my vacation. And in my case, I'd slept on the pullout sofa in the living room for 5 days and was glad to have a real bed too.
Of course, if you don't plan on cooking or making beds while there it won't matter.
3. Since there were six of us this trip, including 4 little girls ages 7-11, we got two rooms at AKL and it felt like we were more spread out, (and were, since our rooms were even on different floors) than all in the same villa together. I had two girls in my room and my friend had two girls in hers. That was half the giggling, half the clothes on the floor, half, well, you get it.
Of course, if you only have four people and are going from a 1 or 2 BR to one resort room it would be different.
4. It seemed to make our trip feel longer with the AKL days at the end. At the end of our 5 days and we were leaving BCV our vacation wasn't over, it was like extra bonus days. Doing the resort days first, I feel like my vacation hasn't started until I get in the DVC unit. I was already in park touring mode and didn't like the "moving" interruption at the beginning of the trip wereas I didn't mind it at the end because I was toured out.
Just my 2 cents. You'll love and have fun at both resorts either way!
