Thought I'd provide a data point here regarding Marriott FNAs if anyone's interested. I earned two FNAs earlier this year from a promo (one of those stay before X date, get 1 FNA, for up to two stays). I miraculously had two stays at the Dolphin back to back in Jan/Feb and earned two free nights as a result. 35k each, can top off up to 50k.
Now, my certs were expiring on 8/24 and 9/1. My plan was always to wait and call right before the expiration and then see if they could extend them about two weeks for our planned stay in
Disneyland that was bookending our Maui trip. Well obviously that Maui trip is no longer happening and we're doing what we can to throw together a different trip. So I called Marriott today and explained I had to cancel a Maui trip and wanted to see if I could get the certs extended a few weeks to allow us time to reschedule a make up trip (sort of true though I was never going to be able to use them in Maui, too expensive). It didn't take too long and he was able to book a two-night stay in LA for me in mid-September (I made this one up on the spot hoping I'd be able to cancel it). He wasn't sure if it would work, just prefaced it with "if the system will allow it."
The system allowed it (he seemed somewhat surprised) and after the call I was able to cancel the booking. The free nights went back to my account and I see they now have a date of 2/21/24. So a six-month extension! I've seen lots of doom and gloom about extending certs and I'm not sure if I got lucky, or if it was because mine were "earned" from a promo and not just credit card annual free nights. The agent didn't give me any sort of hard time or anything, just put me on hold to see if it would work (and it did).
I don't have any accounts on other sites or I'd post about my experience. It does seem like the consensus is free nights are rare but not impossible to extend these days. Either way, thanking my lucky stars as now I can either use these for our real trip in a few weeks or for a future trip, instead of completely losing them. I think having them expiring within a week or two and having a near-term trip "planned" is key, at least that's the advice I've seen floating around.
I'm very tempted by the new Boundless SUB but I'm finding Marriott awards aren't the easiest to use (and the redemptions seem to keep going up, wow) so I need to think on it.
Edit: I had just enough Marriott points to top off a 3-night stay at the Fairfield Marriott just before Disneyland race weekend (coming straight from WDW marathon weekend). So now I’m doing a split stay at Fairfield/Hojo completely on points
Good thing too because these RunDisney races cost enough
