I called Marriott side and they ask me to call SPG side to book SPG legacy hotels. Is it confirmed W and Westin bookable using the 7 nights certificate?

No, it seems to be just Sheraton and 4 points for now, look at the Wiki.

That would be end of November.

any upgrade DP recently?

DP:

Just called to attach my OC5 certificate to a Sheraton property, but unsuccessful.

Since the online system wouldn't let me book a point advance reservation, I had to give CSR the hotel name and dates to book over the phone. This part went smoothly and I now have a confirmation number for a point advance booking, which I can see in my account.

When the CSR tried to attach the certificate, she came back telling me the certificate seems "occupied" currently. After checking with the supervisor, she said it "might" be system migration (probably associated to the Sheraton integration) and there's a good chance I'll wake up tomorrow and find it successfully attached (which I highly doubt). Anyway, I'll call back then, see if things change, and report back here.

The CSR sounded pretty familiar with the certificates, and she definitely knows it has to be cancelled and reordered for the conversion to NC4. So this does seem like a temporary system outage. At least I now have the room secured after the phone call. Anyone having similar issues tonight?

So how much was your cost to ug New 1-4 to 5?

I didn't know they could be upgraded. Would be good to see some more data points on this.

I had success attaching an "old" Cat 1-5 cert to a Sheraton reservation that I had already held with points by sending an email via https://www.marriott.com/loyalty/contact-help.mi asking for that to be done. No waiting on hold, no clueless reps, done within ~8 hours of the request being sent in.

Any datapoints on how long the 30k credit for OC6 (and OC8 etc) takes? contacted through the form three times now over the past month and all I get is an automated reply. Also, any speculation on when (if ever) design properties get released for travel packages? December 11?

That makes two of us. Only other recent DP is the one that says they will be allowed in January.

Check the wiki. You would need to find an agent willing to cancel your OC6 and order you a QP91. This would cost an extra 30k points over the OC6 cert (assuming 7 nights) to switch to an NC5. People have been able to do this since 8/18 but more recently there have been a lot of denials. Most agents have been informed not to allow upgrades so I would not ask for an upgrade. Assuming your cert is unattached I would tell the agent that I understood that I needed to change my old TP cert to a new one in order to use it now, after getting confirmation from them that this is correct to make sure they are not clueless, I would tell them I would like to cancel my old cert and order a new QP91 cert and ask them if they are familiar with the process and can do this for you.

QP91 is an NC5 but given the pushback people have been getting trying to upgrade categories I would not mention the NC5 category. I would just tell them I wanted them to order an QP91 cert (as part of the process to convert your old cert to new cert). I would start with calling a UK agent since previously reports were they were more helpful. You might have to HUCA a few times and it may or may not work. If an agent is unwilling to convert to a QP91 you do not have them cancel the old cert and order a new NC4 cert. Once you get a new cert it is exponentially harder to get an upgrade. Your best chance is to get upgraded when converted from the old cert to the new cert.

7-night packages

• NC4 QP83 = OC5 830T/P830 (refund value: 45K)
• NC4 QP87 = OC6 870T/P870 (refund value: 75K)
• NC5 QP91 = OC7 910T/P910 (refund value: 105K)
• NC5 QP95 = OC8 950T/P950 (refund value: 135K)
• NC6 QP99 = OC9 990T/P990 (refund value: 165K)

So I have converted my OC8 to a new NC6 back in September 2018. Can this be used to attach to a 7 night reservation at a Cat 7 Hotel such as Ritz Carlton Tokyo? The Marriott Rewards agent said not possible, only for New Category 6 hotels. The only way is to either book using 360,000 (5th night free) MR points up to 31 Dec 2018, or book using a New Travel Package (though the current TP are expensive). Anyone had any different experience?
