I disagree with a split stay (although I have one coming up in a week, it just turned out that way, two nights at Pop then 7 nights at AKV Kidani).
I agree that Stormalong Bay in July is not that appealing. I'd rather use a quiet pool personally.
CSR is something to consider - you could look into the concierge level there.
Are exterior corridors a consideration? That is a main difference to me.
Have you considered the Swan? You would lose a few things though, like Magical Express. And you need to consider the added "resort fee" as well. But, the rooms were just completely overhauled and look very nice! I always enjoyed my stays there, and their room service was nice to have a couple mornings and evenings.
I've personally grown annoyed with how much the deluxe resorts are now. I'm renting a one bedroom/two bath unit from an owner this upcoming trip for $250/night versus the well over $600/night Disney was asking. Last spring break it was just DD and me, and we paid $2,000 for BWI. We both agreed it wasn't worth it at all. This upcoming trip it's me and the kids for two nights, then DH is joining us so the space for all 4 of us will be needed!
$1,000 would cover tickets plus a LOT of food and drinks. I'd rather save personally, and choose where appeals to you most. Never stayed at the YC but have stayed a couple times at the BC years ago, and I wasn't thrilled with it much. Preferred for some reason BWI.
Have you looked at redweek for rentals of
DVC units as well? That's where I've rented all but one time (the one time 2 years ago was a last minute off TUG boards).
Edited to add: I see a five night rental at the BCV on redweek 7/15 - 7/20 for $245 a night for a studio. Not sure if that helps much but just looking around! There's also a one bedroom Boardwalk Villa for $400 a night the week before. That's kind of high I think personally, but I love the space of the living room and having my own washer/dryer!
