What are the best hotel promos for September 2025?

Welcome to our regular round-up of the best hotel promotions currently running.

All of the information in this article can also be found on our ‘Hotel Offers’ page which contains details of all of the current offers, together with links to our major articles on each hotel scheme.

However, a positive response from readers – especially our 21,000 email subscribers – means we run this monthly article as a handy summary.

Be warned – it is a very thin selection this month!

Here are quick summaries and links to the registration pages you need for each offer – do it before you forget. (I apologise to email readers if this block is mangled – scroll down to the main text area.)

Where should you credit your stays for September 2025?

Remember that, irrespective of the offers below, there is never a single ‘best’ offer.

Some offers require multiple stays to maximise the bonus, which you might not do. Some require stays to be a minimum number of nights before a bonus is earned.

You need to factor in any elite status you have, which will earn you additional status bonuses.

More importantly you need to be able to use the points. There is no value in earning a large bonus in a scheme where you will never go on to earn enough points to get a free night.

Here are your options:

Hilton (Hampton, Conrad, Waldorf-Astoria etc)

Hilton is offering a one-off bonus of 750 Avios on your next cash stay by 30th September.

The Avios will be sent to a Qatar Airways Privilege Club account, but you can easily transfer them to The British Airways Club.

Registration is a bit of a faff so ensure that you read our article here.

You can register here.

It runs until 30th August. Existing bookings made before registration will count.

IHG One Rewards (InterContinental, Crowne Plaza, Holiday Inn, Hotel Indigo etc)

IHG One Rewards is running a promotion across five brands.

The brands are Crowne Plaza, voco, Vignette, Candlewood Suites and Garner.  You will earn triple base points for stays at these brands until 30th September.

You can register here. Our full article is here.

Existing bookings made before registration will count. The IHG booking page is here.

Radisson Rewards (Radisson Blu / RED / Collection, Park Plaza, Park Inn, art’otel etc)

It’s rare that we feature Radisson Rewards in this round-up but it has launched a multi-brand promotion for the summer.

Radisson Rewards is offering 6,000 to 10,000 bonus points when you stay at two to four different brands by 26th September.

Importantly, only new bookings made after registration count.

We only value a Radisson Rewards point at between 0.15p and 0.2p so this is not a very generous offer. However, if you are doing the stays anyway, you should register.

Existing bookings made before registration do NOT count. The Radisson booking page is here.

And finally ….
