According to Sarasota Magazine this resort is opening August 14th, looks like it's sold out that night but available after that on the website.

I just booked three nights for part of our Spring Break next year, cash rates were over $1,700 per night, emptied out my Bonvoy points at 114,000 points/night. Never been a fan of Marriott, being told I'm still on the hook for a resort fee on a reward stay is yet another reason to not like the program and be glad I'm practically at zero on points now.
