Amex to Marriott and Hilton: When Are Hotel Transfers Worth It?

Cash hotel prices for the summer 2026 season are aggressive. If you are looking at European resorts or US city breaks for the upcoming school holidays, the numbers on your screen are likely making you wince. At the same time, thanks to the recent boom in American Express supplementary card bonuses, many Points Uncovered readers are sitting on an unexpected influx of 10,000 to 30,000 Membership Rewards (MR) points.

The temptation to funnel those points straight into a hotel partner to soften the accommodation bill is huge. We usually tell you to send your MR points straight to Avios or Virgin Points because the maths dictates it. Today, we are looking at exactly when breaking that rule makes sense, and when transferring your Amex points to a hotel scheme is a terrible waste.

The raw 2026 transfer maths for UK Amex cardholders

To understand if a transfer is worthwhile, you have to know the baseline value of your points. A UK Amex Membership Rewards point should be valued at a minimum of 1p. You can reliably achieve this by transferring to British Airways or Virgin Atlantic and booking reward flights.

When you move points to hotel partners, the transfer ratios muddy the waters. Here is exactly what you get in the UK as of April 2026:

• Hilton Honors: 1 Amex MR point = 2 Hilton points
• Marriott Bonvoy: 2 Amex MR points = 3 Marriott points (a 1 to 1.5 ratio)
• Radisson Rewards: 1 Amex MR point = 3 Radisson points

To break even on that 1p MR valuation, you need to achieve 0.5p per Hilton point, 0.66p per Marriott point, or 0.33p per Radisson point. This is where the problem starts.

The 2026 average value for a Hilton point is closer to 0.35p. A Marriott point averages around 0.5p. This means that a speculative transfer for a standard hotel stay usually represents a straight loss of value. You are taking a currency worth 1p and turning it into a currency worth 0.7p to 0.8p.

When does transferring to Marriott or Hilton actually make sense?

There are specific scenarios where moving Amex points to hotels is highly strategic. You just have to know what you are looking for.

The top-up strategy

The absolute best use of MR points for hotels is the top-up. If you hold 220,000 Bonvoy points earned from actual stays and you need 240,000 for a specific redemption, you are short. Transferring 14,000 MR points to get those final 21,000 Bonvoy points is a smart, low-waste move. It unlocks a high-value redemption you otherwise could not afford, without draining your entire Amex balance at a sub-optimal rate.

High-demand event dates

Standard valuations break down when cash prices detach from reality. If you are trying to book a hotel in a city hosting an F1 race, a major tech conference, or a massive stadium concert, cash rates often triple. Hotel points requirements, even under Marriott’s fully mature dynamic pricing model, usually do not spike quite as aggressively. In these extreme scenarios, you can easily achieve 1.5p or more per MR point on a hotel transfer.

Ultra-luxury redemptions

The maths often works at the very top of the market. Booking the newly opened W Prague, which currently goes for around 60,000 Bonvoy points a night, can yield excellent value compared to the cash rate. The same applies to high-end Maldives resorts or the newly live Hilton integration with AutoCamp for luxury glamping. If the cash rate is astronomical, the points rate might just justify the transfer.

The magic of the fifth night free

Both Hilton (for Silver members and above) and Marriott offer a fifth night free on reward stays. This effectively boosts your points value by 20% on exactly 5-night redemptions.

If you hold an Amex Platinum card, you automatically have Hilton Gold and Marriott Gold status. You already have access to this perk. Never use points for a 4-night stay. Pay cash, or stretch your trip to 5 nights to get the mathematical boost. That 20% uplift is often the exact margin needed to push a hotel transfer from a bad idea into a good one.

Why you should ignore the Amex Travel portal

Booking hotels directly through the Amex Travel portal using your points is a trap. You get a fixed rate of 0.45p per MR point.

If you have 100,000 MR points, the portal will give you £450 off your hotel bill. If you transferred those same 100,000 points to Avios, you could comfortably book a long-haul flight worth £1,000 or more. Even transferring to Hilton and accepting a poor redemption rate will usually net you 0.7p per MR point, far beating the portal. Ignore the portal entirely for hotel bookings.

Hidden traps and fees to watch out for

Before you hit the transfer button, there are a few realities of the hotel points game you must accept.

One-way traffic

Transfers are irreversible. Once your MR points become Hilton Honors points, they can never go back to Amex. You cannot efficiently move them to an airline later. You must be absolutely certain of your booking before you transfer.

Fortunately, transfer speeds are fast. In 2026, UK Amex transfers to Marriott and Hilton are typically instant. You can find availability on the hotel website, log into Amex, transfer the points, and book the room in the same browser session. Radisson transfers are the exception, sometimes taking up to 48 hours.

The resort fee divide

Hilton famously waives resort fees on reward stays. Marriott does not. If you transfer points for a US property, be prepared to be hit with a daily destination fee of $40 to $50 at checkout. Always factor this cash cost into your cents-per-point calculations.

Premium room traps

The maths on standard room redemptions can sometimes work. The maths on premium room rewards is almost universally abysmal. Hilton’s algorithm regularly asks for hundreds of thousands of points for marginal room upgrades. Only transfer your Amex points if you are booking standard room availability.

The airline alternative: Avios and Virgin Points in 2026

The opportunity cost of transferring to hotels is unusually steep right now. The airline side of the points game is highly stimulated.

Virgin Atlantic has doubled its credit card bonuses, offering up to 36,000 Virgin Points. British Airways recently launched 40% Avios buy-bonuses amidst their A380 route reshuffle. Transferring your Amex points to airlines reliably yields 1p to 1.5p in value, often much higher for long-haul business class. Flights win the valuation battle 90% of the time.

The honest verdict on Amex hotel transfers

Honestly, I am not convinced the maths works for most people. Unless you are topping up an existing balance or booking exactly five nights at a high-end property, transferring Amex Membership Rewards to Marriott or Hilton is a quick way to devalue your hard-earned points.

If your primary goal is free hotel nights, earning 1 MR point per £1 on a standard Amex and transferring at 2:3 to Marriott is incredibly inefficient. You should be holding the UK Marriott Bonvoy Amex, which earns 2 Bonvoy points per £1 directly.

Save your Amex points for flights. Pay cash for your hotels if you have to, and explore more guides on Points Uncovered to make sure your next redemption actually hits that 1p valuation floor.
