Looks like I got Bonvoyed! Been planning a big spring break vacation for the family for NEXT year. Got up this morning to book the room (first day it's available). Nope. No availability. Good thing I got Titanium status along with my Lifetime Platinum and generated all of those points in my account.

For the record, I attempted to book:
JW Marriott Marco Island
Westin Grand Cayman
Marriott Grand Cayman
Atlantis (any of them)
RC Amelia Island
RC Fort Lauderdale

No availability at any of those.
