I never knew there was a Four Points at Nashville Airport. After some google searches I realized it is the old Wingate. Also based on the trip advisor reviews I'm not sure this hotel should have gone up a category. Until I see some improved reviews, I think I'll continue to use the Hyatt Place Airport or the Sheraton Music City.
I too am glad to see the Maui properties go back down. With all the new flashy resorts on the south side, it's hard for the older (but still nice IMO) SPG resorts to compete. Lowering the category is a good start.
