UPDATE – JUNE 2025: This Marriott article is now out of date, but don’t worry. We produce a monthly summary of the top hotel bonus point offers – please click HERE or use the ‘Hotel Offers’ menu above.
SPECIAL OFFER: Until 15th July 2025, the sign-up bonus on the Marriott Bonvoy American Express Card is TRIPLED to 60,000 Marriott Bonvoy points. This would convert into 25,000 Avios or into 40 other airline schemes. It would also get you at least £300 of Marriott hotel stays based on our 0.5p per point low-end valuation. Other T&C apply and remain unchanged. Click here for our full card review and click here to apply.
Marriott Bonvoy is offering a 30% to 50% bonus (varies by individual) when you buy points by 16th July 2025. Click here to buy.

We thought that the recent deal for buying SPG points would be the last before Marriott Rewards and Starwood Preferred Guest were merged – but it is back. This time it MUST be the last time, as the two schemes merge in August!
This is a reminder that you can currently buy Starwood Preferred Guest points at 35% off – the link is here. 30,000 SPG points will cost you $682.50 (£514).
30,000 SPG would convert into 90,000 Marriott points. This is an excellent deal when you remember that NO Marriott or Starwood hotel will cost more than 60,000 points per night if booked between August and December (stay whenever in 2019).
You need to buy via this page before 20th July.
PS. This is also a way of buying airline miles in schemes that do not sell miles directly, such as Lufthansa Miles & More. Starpoints transfer at 1:1 to most airlines and you receive a 5,000 mile bonus when converting 20,000. You need to do the maths but buying SPG points at 35% off could work out.
