MGM room booking question……

Question

So I booked a comped room at Vdara about 2 months ago. I was just poking around on the MGM website and for the same dates, if I wanted another room at a different property, I would have to pay. I knew this already.

But, the Cosmo was available to be booked as a comped room. So I booked another room at Cosmo, Terrace Studio, all comped. Does this sound right? Never ran into this before…thanks

Answer

You’re asking a very good question — and the short answer is: yes, it’s possible what you did (booking a comped room at and also booking a comped room at (“Cosmo”) for the same dates) — but it’s a bit of a grey-area, and may depend on whether it’s a legitimate “offer” or a temporary glitch. You should know there’s some risk involved. Below is what seems to be understood among Vegas players, plus what to watch out for.

### ✅ What makes your situation plausible (and why some people report it works)

There have been multiple reports from people claiming they managed to book simultaneous comped stays at different properties. For example, one user wrote they had a comped room at Vdara and then found that “Cosmo was also available to be booked as a comp during the same time (with only one-day difference),” and checked in to both without “problems.”
Some people say this was possible because at the time there was a “glitch” in the booking system — often involving Cosmo — that allowed overlapping comp bookings. > “the Cosmopolitan glitch … you can currently double book two hotels, but only if one of them is Cosmo.”
It appears that during a window of time, at least some users successfully stayed in both rooms and their comp stays were honored.

### ⚠️ Why this may *not* be “officially” allowed — and what can go wrong

According to many recent reports from other users and on discussion boards, it’s more common now for the system to block a second comped room if you already have one booked. In some cases you get an error when trying to add the second room (“offer you are applying overlaps …”) which suggests the policy has been tightened.
Some folks say that even if the booking “goes through,” there’s a chance the second comped room could be cancelled later — especially after the company corrects any glitch or merges reservation systems.
There are terms and conditions tied to comp offers under the loyalty program (MGM Rewards for MGM-owned properties, and Identity Rewards for Cosmo) that typically only allow one comp-room at a time per account, or require a gap (e.g. 72 hours) between separate comp-bookings.
Even some regular Vegas travellers say that this “loophole” has been closed: newer posts say booking two overlapping comped rooms via your account no longer works.

### 🎯 What I think is going on — and what you should do to protect yourself

It’s likely that what you found — comped Terrace Studio at Cosmo for the same dates you already have a comped Vdara room — is due to a temporary loophole or glitch in the booking system (historically related to Cosmo + MGM integration). It hasn’t always been strictly by the written policy, and many who tried it only got away with it because the system didn’t catch it. Some of those travellers reportedly were honored, but there’s no guarantee the offer will “stick.”

If I were you and I did this, I’d do the following to minimize risk:

Call or email MGM/Identity-Rewards customer service (or check with your host, if you have one) to confirm both reservations are valid and that they won’t cancel one because of overlap.
Have separate payment/credit-card holds for each reservation (since each room usually gets its own incidentals hold, which people in forums often mention).
At check-in, be prepared for the possibility that hotel staff might question or cancel the second room — have a backup plan (e.g. being prepared to pay or shift to a paid rate if needed).

### ✅ My opinion — It’s “risky but possible,” not “guaranteed safe”

I think what you did can work — and many people have reported success — but I’d consider it a bit of a gamble. The fact that others got both comped stays honored gives hope, but the number of reports warning that “the loophole was closed” suggests that you’re no longer in a reliably safe zone. If I were you, I’d keep both reservations for now, but treat the Cosmo booking as “potential bonus” and not count on it 100%. Confirm with MGM if you can, and prepare for either outcome.
