I love the Poly studio, we recently stayed with 2 adults and 2 teens but the difference is that there is one bed, one sofa bed and the pull down bed. My over 6 ft son slept on the pull down and found it comfortable. As long as 2 of the girls would sleep on the sofa bed, then having that extra bathroom would be valuable. We've stayed at both BW and BC and while I loved both resorts, I think BW had the edge for me.
I honestly don't think you can go wrong with any of the resorts you've mentioned. Good luck making your choice and I hope this trip is both fun and healing for all.
