We bought sight unseen... stupid I know but we did. We purchased BLT (180) and AKV (200) add on during a holdiay webcast special. I would have added more BLT if I had already been to both.
Our trips to date include - March BCV 4 nights and AKV 8 nights Oct 2 nights Poly and 6 nights BLT
AKV was not my favorite. It could be that the stay was too long, perhaps the fact it was FREEZING or the fact I broke both of my thumbs on day 3 bracing myself from a fall but it was just ok. To be fair we liked walking to BCV but our villa was worn down so that wasn't our fav either.
Oct was warmer and we LOVED BLT. Walking to MK was such a benefit! It may have been that we were more comfortable, I didnt get hurt and it was warmer but I am SO happy I bought there.
There are so many more resorts for me to visit but I think the only other I would be intersted in purchasing may have been BWV. We havent been there yet so I can't comment.
So the long story short... Go to the resorts, experience them and then decide. If you can rent points or pay cash to stay at a
DVC to try it out do that first. Don't jump into it and take your time.
My regret -I wouldn't have purchased AKV it was nice at first but I can book a savanah view at 7 mo so I dont need home resort for that one. I would have put more into BLT or another resort instead maybe. I got "add-on-itis" too quick.

Would I turn back the clock and not buy... HECK NO! I didn't take a vacation for 10 years. This will in a way "force" us to go on family vacations. I am happy with my purchase just maybe not my locations
