No, not possible
You have to factor in all kinds of different..... well factors.
When did the reviewer go. There might be times of the year when Wailea is better than Kapalua, but only a couple of months.
What are the reviewers expectations. A person who stays at Ritz's a lot might be more critical and have higher expectations. What would that frequent Ritz stayer think of the Marriott? I am afraid they'd be disappointed.
By the same token, what is your average Marriott guests expectations? Compared to the Chicago Marriott and Kansas City Marriott and Anaheim Marriott, the Wailea Marriott must seem Ritz like. All reviews at a place like TripAdvisor and similar places show is how well a hotel meets the guests expectations, not an objective rating of a hotel or restaurants. It how places like Olive Garden and PF Chang's can be highly rated on those type sites.
I think there is no comparison between the Ritz and Marriott Wailea. If I was going to winter, I'd look at use my Marriott points at the Marriott in Ka'anapali.
