As a newly minted Lifetime Platinum member my suggestion is to allow Platinum members to have a day of arrival cancellation policy instead of 1 day before arrival.
I often need to change directions and the new 1 day before arrival cancellation implemented this year makes it difficult for me to reserve in advance. Platinum members don't cancel without reason and stay a significant number of nights each year. I find the new 1 day before arrival policy to be overly restrictive and this simple benefit would bring back the experience to which I've become accustomed over the past 14 years of membership.
