Agreed, all good considerations. Just pointing these out for OP as they're considering a potential BCV purchase/rental strategy for the future. Luckily BCV is low on my priority unless, that is until the little ones are old enough to enjoy Stormalong Bay!
For me, Stormalong Bay has actually become a negative. It was GREAT when my kids were adolescents to tweens....
But now that my kids are older teens, and more off on their own, we don't need to sit around with them at an overcrowded overly loud quasi-water park.
Which raises a good point -- When picking your home resort (and deciding whether to purchase DVC at all), one should consider that their preferences may change over time. I see a lot of people say, "we want a Magic Kingdom resort because we have little kids and MK is the best park for them" -- But those kids only stay little for a few years. Kids grows. Family size changes (as do the need for different sized rooms). It can be really challenging to do it, but it's important to try to think long term preferences.
If I had purchased in 2010 instead of 2019, I probably would have purchased BLT or Beach Club. I ended up purchasing Riviera, and at this stage in my life, Riviera is a lot better than BLT or Riviera. (and hopefully, that's the way I still feel in 10 years.)
