Yes.
If one does pay ADVANCE Rates that is 20% off.
AAA rates are 10% off

Well, maybe it was a temporary glitch or some sort. A few days after the above post one Comfort property started showing up in (SOS aka) SC15 searches in SoCal, and then a few days later a second one, and then I just tried the other day and pretty much all the properties I used to see before I see again in SC15 searches.

So my SC15 panic is over!

Btw, in the process the one hotel which used to give 20% off for SC15 has been fixed to give only 15% off. So maybe this was a process to have each hotel re-enter the SC15 rate correctly?

The OP's code could have been in the "VIP" (as opposed to "SOS") category. This is how Choice has classified some corp/org codes that bore the 20-25% (and greater?) discounts. Sometimes these VIP codes have required a phone call to reservations. I haven't tried re this one, but someone might.

Unfortunately, as in recent experience, VIP and SOS rates have been the same, making the distinction moot. (And then the occasional disappearances altogether. Can something be more moot?) Some have speculated that this and other troubles we have are the result of the FlyerTalk Pogo Effect -- e.g., "we have met the enemy and it is us" a propos of discussion here. Some have speculated, rather, that it's the loose ChoiceHotels system, as reflected in sdsearch's many valuable analyses.

I can't figure out what you're saying for the life of me.

Anyway, now that we've established (concretely rather than conversationally) that the Century 21 code is definitely totally dead, what is a specific working SC15 code?

Not sure why you would expect someone to give you a code that you are not entitled to.

If these codes are simply posted on a public site, then they will go away.

Oh good lord. People do that here constantly. It's the main reason why flyertalk.com is a destination. What you're really saying is that you want to pick and choose who's in the club.

Anyone else?

We don't want to post a specific SC15 code, because then everyone will use that one code, and it'll get killed within weeks.

Instead, search online for "Choice discount code" or something like that, when you have time to go through many pages of results, and you'll find some. They probably won't spell out "SC15" (because that's a term you only see on Choice's website); you're more likely to see "SOS" (Significant Organization Savings), which was the old name for SC15 rates. It used to be that, among other things, you'd get a lot of state and local farm bureaus in such a search. (I don't know if you still do or not.)

Also, I said "5 digit" above, but I now remember than many of the SOS / SC15 codes actually have several leading zeros (which you can leave off when entering the SC15 code on the Choice website).

But sometimes I do get asked (though just casually) about the company/organization that comes up on reservations when I use the SC15 code. (Yes, my checkout folio often does claim I'm from the organization whose SC15 code I used.) So just be prepared to answer reasonably if someone ask you about the company/organization whose SC15 code you used. What you don't want to do is say "I don't know who the hell that is; how did that get on my folio?"!

There's differing consensus in the different forums w/r/t sharing discounts, and the anti- has prevailed on this board. A couple of points to keep in mind: The vendors usually don't like it. Early in the frequent traveler game that has evolved to FlyerTalk*, there was a guy who researched and publicized the discount codes provided by American Airlines to preferred organizations. AA squelched him. The meeting & travel planners and the like at the organizations that contract for the codes very definitely believe "the more the merrier". But the debate goes on, at least in this forum.

* Mr. Petersen largely perfected the game by (rarely publicly saying ill of and...) persuading the vendors that if they've set the bar right with their discounts and promos, the more business that is generated, the better.

Well, as for the subject of this specific thread, it seems that all working corporate/Net VIP/SC-15 rates are mooted by this publicly available offer that also earns 3.5% cash back: http://focuspull.in/EBates. You just sign up and search for Choice Hotels, then click through and you'll find that an "Internet" rate is pre-filled in, at the same discount as the others (but with an extra 3.5% cash back). Best available for now.

But is it the same terms as the others? Ie, the SC15 rates have the same cancellation terms as Best Available Rate. And at some other hotel programs, the "internet" rate is a non-cancellable rate.

And how does logging in work? Do you log into Choice after you click through from EBates? Does logging in not make it lose the rebate or the selected "internet" rate? (Without logging in when making your reservation, you won't get 8000 points for every 2 "trips". And an extra 3.5% cash back is not worth as much as the 8000 points promo, IMHO.)

I wonder about this, too. Elites have a broad privilege w/r/t where we can book and have it count. Not sure if it extends to this path.

You should just try it (explains itself). You'll find that after creating an eBates account, and clicking through, you're offered rates that match the existing alternative ones under their own tab, with unrestricted cancellation. The 3.5% bonus operates independently of that.

I'm not interessted in giving that website my email address if it turns out I'm not going to be able to use it. (And I can't seem to get much of any information out of that website without poviding my email address.)

And you still didn't explain about the logging in.
