I don't see why Marriott would prevent future upgrades. No real arbitrage opportunities there either way.

For higher categories that don't have a 1:1 conversion to a new category, my guess is that people will get a half-category one-time gift.

On one hand, this is a pretty niche issue. It's not like there are millions of these certs out there. But...anyone who has one is somewhat by definition a somewhat high-value customer for Marriott going forward. So the incentive to treat people fairly should be there.

You have to call to get your certificate back. If you cancel your reservation online, you don't get the certificate back.

Will that extend the expiration date?

No, extension is not automatic, unless you make another reservation for stay beyond the current expiration date.

5-night upgrades
 

I know that in the past 7N packages have been able to be upgraded by paying the appropriate difference in points between the old and new packages. Is the same true for 5N packages? I have a couple of 5N cat 1-5 packages that I'm planning to hold on to through the transition, but I'm very low on points, so I'm debating whether or not to buy some SPG points now in order to (possibly) have the ability to upgrade it later this year (no firm plans so can't book now).

Can we detach the certificate (by calling) without canceling the reservation?

Today I noticed that my 7 night floater cert which had a surrender point value last week of 45k points, is now showing 55k points. I wonder what that's about?

They're upgradable, at least before August, if you still own Marriott timeshares. After the two programs merge in August, it's not clear the new TP certificates will still be upgradable, or even your current 5-night certificates will still exist.

Thanks

Most likely an IT issue, but who knows. Even if Marriott has decided to refund you 55K points when the certificate is cancelled in August, you'd think they won't let it slip this way.

I try to get the package for 120k Aeroplan with 7 night, but on the flight and hotel package site I don't see the option to redeem for Aeroplan except Air Canada. Anyone in the past able to redeem for Aeroplan? do I just call and say redeem for Air Canada? thank you!

Air Canada is Aeroplan until they introduce their own FF program in 2020.

Where did you look too see this? All I can see is that I have a 7 night cat 1-5 travel certificate and the expiration date but I cannot see such details like surrender value?
Thanks

Only after the certificate has been extended or detached from a reservation.

So I just say to the rep i want to transfer to Air Canada then the point will be in Aeroplan? I just want to make sure before I go this because I don't looking to get Air Canada mile? thank you!
