Bet You Didn’t Know: Maximizing Marriott’s 5th Night Free on longer stays

By Julian, author of Devil’s Advocate


Not a day goes by when I don’t think to myself, “man, it would be really cool if…” followed by some sort of very basic and totally logical innovation. You know, something along the lines of “man, it would be really cool if Delta’s newly fixed online award redemption system was actually fixed and not just a little less broken than it used to be.”

This happens to me in all areas of my life, but never more so than when I’m planning a trip. So it’s a pleasant surprise when I wish for some sort of simple tool and then discover it actually exists. My recent post about automatically piecing together complex itineraries with Google Flights is a case in point (see “Bet You Didn’t Know: The magic of Google Flights“).

Today’s tip is another great example. If you’re like me and you have a decent collection of Marriott points (or so many Ultimate Rewards points that you don’t know what to do with them all and you’re actually willing to transfer some to Marriott), you likely already know about Marriott’s 5th Night Free deal. If you redeem points for 5 or more nights at a Marriott in a single reservation, the 5th night is free. This is a terrific way to maximize Marriott points by effectively cutting the cost of any 5 night redemption by 20%.

Because of this 5th night bonus, I personally like to try and use Marriott points for stays that are at least 5 nights and use cash or other hotel points for shorter stays. However, when you redeem at Marriott for stays longer than 5 nights, you’re essentially diluting that 20% points savings for each night beyond the first 5 (at least until you get to 10 nights, at which point you’re not only getting the 5th and 10th night free but you’re also so tired of spending so many nights at the same hotel that you’d pay a million extra points if you could just finally go home and sleep in your own bed).

Happy to be sleeping in his own den after 10 nights at the Courtyard by Marriot Orlando (though he still loves Space Mountain).

But here’s the good news — if you’re willing to mix in some cash with your points, you can maximize that 5th Night Free benefit at the full 20% savings and still get a stay longer than 5 nights.

Here’s the even better news — when you combine cash and points in the same reservation, the nights you’re using points for do not have to be consecutive. So you can pick the nights with the lowest rates as your “cash” nights.

And here’s the best news — Marriott has a tool on their website that will figure all this out for you automatically.

Marriott wants to save you money. Really.

Let’s look at an example. My friend Omer is sitting on a stash of 140,000 Ritz Carlton/Marriott points (wonder where he got those from) and is getting ready for a 7 night trip to London in May. Hotels rates in London can be super expensive, especially when you convert British pounds to U.S. dollars (though not as bad as when you convert chocolate ice cream pounds to my bulging waistline! Hey now! OK, folks, not every joke in these posts can be brilliant.)

This seems like a perfect opportunity for Omer to use his Marriott points. So we bring up the reservation search system, punch in his dates, select “Use rewards points” as an option, and fire away…

Hmmmm. Those are some pretty expensive hotels and they want a lot of points for them. Even with one night free on a points redemption (which Marriott has already figured into these search results), it’s still going to be significantly more than 140,000 points at even the cheapest London area Marriott.

But all is not lost. We know we want to maximize our 5th Night Free benefit, so let’s pick a hotel that we know would be 140,000 points for 5 nights. That’s a simple matter of dividing our current points results by 6 (since one night out of the 7 is already free) and then remultiplying the result by 4 (to account for a 5-night reservation with the 5th night free). OK, so maybe it’s not a simple matter. I suppose we could just look up the hotel categories on the Marriott chart instead, but trust me, this is the right calculation. I think. Dammit, where’s the quadratic equation when you finally need it?

Anyway, we’re looking for hotels listed at 210,000 points for 7 nights (which are category 7 hotels for those of you scoring at home), so let’s say we decide on the Marriott Kensington. We click on “View Rates” where we can book with 210,000 points as expected.

But there’s an option at the bottom of the screen to mix cash nights with points nights. It’s the plus sign next to the words “Use Cash + Points.”

By clicking on that option, we get a calendar of our stay where we can change any number of nights from “35,000 points” to “Cash Rate.”


Which nights do we choose?

We could manually check each of these nights to determine the cheapest, but instead let’s just try the last two nights after the Free 5th Night. That gives us the 140,000 point redemption we’re looking for plus a cash outlay of 438 British pounds for the extra two nights.

Notice the box that’s suddenly appeared next to the Cash + Points box that reads “Save”?

That’s informing us that there are two nights in our stay with a lower cash rate than the ones we’ve chosen. Which means all we have to do is click on that “Save” box and let Marriott do the work…


It turns out the 4th and 5th nights of our stay are the cheapest nights, not the last two, so Marriott has altered our choices to give us the cheapest rate. Note that we are still getting our Free 5th Night even though we’re splitting our points nights in half. It’s just moved to the end of the reservation instead of being on the actual 5th night. Our points outlay is the same but now our cash portion has dropped to 320 British pounds. That’s a savings of about $180 at today’s rates.

Finishing up…

From here we can click the big blue “Select” button and finish up our reservation, where we’ll see the final breakdown of the price…


Since this is a points reservation, it allows cancellation up until 4pm local time on the day of arrival, which gives us fantastic flexibility. If we had booked the Advance Purchase rate for the same nights, we would be stuck with an unchangeable reservation and would have paid this…


That means for our 140,000 points, we saved 882 British pounds, which is around $1,340. That’s nearly 1 cent per point in value. For Marriott hotel points, that’s pretty darn good.

So if you’re sitting on a slew of Marriott points, don’t fret if your stay doesn’t add up to exactly 5 days. Put a little cash towards the problem and let maximize both your points and your money.

I didn’t know this… but I have approximately zero mariott points (well, maybe 3000?) so it’s of little use to me right now. Maybe if I got off of my &*! and found myself 140,000 ritz carlton/mariott points too, I’d be able to make use of this information. (new year’s resolution?)


That was very cool, well done! Bookmarked for future reference absolutely.


Great work Jullian, I didn’t know you could mix paid and award nights to get 5th night free. Pretty clever!


But don’t actually stay at the Marriott Kensington – it’s not a great hotel, even as an Elite.
County Hall is in the same category and a much better bet.

Nice tip though.
