I'd go with BLT in a heartbeat and second what was said about a BLT lake view. It's actually my favorite view after the BW view over at the Boardwalk. I think it's really underrated.
We just stayed in a BLT studio and found it to be fine. The dresser was a little dinged up, but nothing else was overly shabby. That walk to MK made it worth it, and then some.
As far as pools go, I was out on our balcony quite a bit and the kids looked like they were having plenty of fun at the pool. I often think we overrate certain pool features as adults. Kids mainly want water and a slide, and this one'll do the trick.
