As I know already aproved LNF rates can be canceld but not changed. But try it, Marriott customer service sometimes very generous.

If you still can choose/change, take the Renaissance and cancel JW.
I stayed in both, the Renaissance is much more better then the JW and I would never pay more for the JW then for the Renaissance.

thanks. I sent an email but no answer. I call and they told me that some times is possible and other times is not possible.
About Bangkok, I should stay in BKK for 1 month, so I'm looking for a good offer. Renaissance is my first choice as it's the closest marriott hotel for my purpose (with the courtyard as well), but it's really too expensive. With No Look Further rate I get a good rate for about half stay.
Tried to contact the hotel directly, no reply yet.
I tried to make multiple reservations and ask for the look no further rate (since I found a lower rate, but they deny) and I received not so "nice" reply (I know that I made too much reservation). I understand that is not possible make multiple reservation and ask for the NLF rate, so I really don't understand how it works. Maybe, MAYBE, to change a reservation you can write to their email address.
One year ago I obtained a NFL for Cosmopolitan Las Vegas. I made two separate reservation and they join them telling me that I can modify with no problem.

Sort of weird situation here-- refundable price when booked directly is $132/night. NONrefundable price when booked directly is $161/night. Price on hotels.com for NONrefundable is $115/night and refundable is $144/night.

Clearly the refundable rates wouldn't be eligible, but the nonrefundable rate is massively eligible as the cheapest of all options.

Is the only option to proceed truly to book the $161/night rate on marriott and request & hope?

If you deny the breakfast benefit at a hotel that gives you breakfast in the restaurant you get 750 bonus points. For $10 I'd keep the breakfast rate and get the points instead.

I for one am glad you posted this. I have a hotel where I've found a lower rate but they're not offering any non-package standard rates. They have a rate with nightly hotel credit and the Marriott rate. Now I know I need to search for a different hotel because neither of them will work. I'm sure the hotel knows there's an LNF out there and they're trying to prevent it from being approved.

Every time they accept my request without any problems !! But this time they want me to register and make a a reservation with the other website which is just waste of my time to give me the rate i dont have the time but i also found cheaper rate at booking lets see lolol

I well get the rate plus 25% i know it if not i well cancel my booking and stay some where else

If you find a rate at booking, then it's a sure win. Marriott approves all major OTAs without a fuss.

Yes but they take long time to replay, i well pay fees if i keep it 3 hours more canceled the booking and book other place marriott just lose my $ to them ..
They must make it faster to replay to us they are very slow ..any way booked at SPG with better price and better location for me

I'm new to Marriott's LNF (much more accustomed to SPG's BRG). I found a rate on skoosh.com with the following cancellation policy.
I cannot find a 5-day refundable rate on marriott.com - can I just use the standard 1-day refundable rate for the claim? Does the fact that skoosh.com charges right away change the LNF possibilities?

I should have read your advise earlier. I booked the lowest available rate (Members Rate) and filed for a claim. It went through without as much as a blink of an eye. Three days later I booked another day (one day in between stays) using the same Marriott Member Rate and the LNF claim came back with

However, it continued with

So the LNF went through anyway, and from now on I know that my life is even easier when I only have to match the standard rate, rather than the discounted Marriott rate...

HTB.

They LNF agents don't seem to care about cancellation policies in general. I have never had one rejected for that reason and I've submitted a bunch. The word "coupon" on the OTA site is more likely to cause a rejection.

Is it just me, and maybe the fact that I'm on mobile browser, but the coupon restrictions seem to have disappeared from the t and c's?

The restriction disappeared a while back ^

You mean I can use a promo code rate ( for example an orbitz 10% off) as my comparison?

A few years back I was denied due to room rate was same before taking coupon into account.

I mean that voucher sites that typically weren't allowed outside North America are now allowed as comparisons...
