We all hope that this will be changed one day. It is one thing that would make us accept the reservation that much quicker and would benefit everyone because if they have less than stellar reviews.....guess what....I am cancelling them anyway and taking a hit on my ranking. Does that seem even remotely right? Bad guest, yet I take the hit. Hmmmmm?
As for giving the rating. I always do in the hopes that one day it will be available immediately to us before accepting the reservation, but even with it as it. I breath easier after the booking if the reviews (or bubble rating as Margaret pointed out) is all good!!!!
