My 2019 IHG unrestricted free night just posted. It did overlap so I have 2 nights in my account right now. Trying to decide if I see if 2018 can still be booked for a date after expiration and use them together for a later trip. Downside to that is if we have to cancel I lose my night. Bit of a gamble.
We have a quickie trip to Vegas we're debating, and if we decide to go I can try for the Palazzo - which had been my plan for the next trip out there, until IHG went cheap and restricted them

That's very tempting but so far SW points pricing has not been favorable so that's a gamble too... thinking about it, I guess that's fitting...
