Some consider the Luau PVBs signature since it is priced as one. But yes, not all have everything.A signature TS, a regular TS and a QS ..... better than BC, BW. Poly has no signature, AKL has an extra TS across both Jambo and Kidani.
I personally do not see the step back in rooms. The theme at BCV is lesser to me than RR, but still, well done. We loved the subtle touches. PVB blew us away. CCV is above BWs most recent refurb in feel. I dislike the white bed look, but otherwise love the new feel they are putting in rooms. We've lost the over the top touches like pink towels which I am glad for. I do miss warner bedding though. If not in a 2 bedroom or double studio at PVB where we have spare blankets, I have to call for more.
