neither my kids, nor my (young) nephews cared for SAB (with multiple vacations at the BC, YC, & BCVs).
the biggest complaint was that it is simply too crowded (all have been swimming since they were little ~ pools, bay, & ocean).
otoh, they all love luna park (easy access to slide, can actually
swim and/or play without bumping into people).
personally, i like luna park much more than SAB also (too noisy & crowded for us), but prefer BW's "quiet pool" most of all
(& yes, we found the BCVs & BC both in- & outdoor common areas (lobby, hallways, etc) noticably more noisy & "busy" than other
DVC or deluxe resorts. however, the YC is much more serene than its sister resort).
