Koh Samui is Thailand's second-largest island -- a Gulf of Thailand gem with coconut palm beaches, a mountainous jungle interior, and some of the best luxury resorts in Southeast Asia. The points angle? Four different loyalty programs have properties here: Hyatt, Hilton, Marriott, and IHG. That kind of program diversity is rare for a single Thai island.
The only existing points guide for Koh Samui is a stale Upgraded Points article from September 2025. Here's the updated picture with current pricing from our database.
All points prices below were verified in our Itravy database on March 22, 2026. All four programs use dynamic pricing, so rates may shift depending on your dates and demand -- but these numbers give you a reliable baseline for what to expect.
1. Hyatt Regency Koh Samui -- 20,000 World of Hyatt Points
Points: 20,000/night | Cash: $274/night | CPP: 1.4 cents
The clear value winner. The Hyatt Regency Koh Samui opened relatively recently and sits on a hillside above Chaweng Noi Beach -- one of the island's best swimming beaches. The resort features cascading infinity pools, a spa, and multiple dining options with ocean views.
At 20,000 Hyatt points per night, you're getting 1.4 CPP -- the best redemption value on the island and strong by Hyatt standards. Because Chase Ultimate Rewards transfers to Hyatt at 1:1, those 20,000 points come directly from your Sapphire Preferred or Reserve card.
Transfer path: Chase UR -> World of Hyatt at 1:1
2. Conrad Koh Samui -- 110,000 Hilton Points
Points: 110,000/night | Cash: $975/night | CPP: 0.9 cents
The luxury splurge. The Conrad Koh Samui is one of Hilton's flagship Asian properties -- every room is a private pool villa perched on a hillside overlooking the Gulf of Thailand. You get your own infinity pool, a spacious living area, and some of the most dramatic ocean views on the island. The resort's Jahn restaurant serves elevated Thai cuisine and the spa is world-class.
At 110,000 Hilton points, the CPP is 0.9 cents -- strong for Hilton. But here's the real math: Amex MR transfers to Hilton at 1:2, so those 110,000 Hilton points cost just 55,000 Amex MR. A $975/night villa for 55,000 Amex points? That's effectively 1.8 CPP on your Amex MR -- exceptional.
Diamond status (automatic with the Aspire card) gets you complimentary breakfast, lounge access, and potential villa upgrades that push the value even higher.
5-night stay with 5th free: 440,000 Hilton points (220,000 Amex MR) = $4,875 in value.
Transfer path: Amex MR -> Hilton at 1:2 (55,000 Amex MR per night)
3. W Koh Samui -- 79,400-82,400 Marriott Points
Points: 79,400-82,400/night (dynamic) | Cash: $605-723/night | CPP: 0.8-0.9 cents
The W Koh Samui delivers that signature W energy on a private stretch of Maenam Beach -- every room is a villa with a private plunge pool. The property has a beachfront infinity pool, a lively bar scene, and the kind of design-forward aesthetic that W does best. It's the most "Instagram-ready" property on the island.
At 79,400-82,400 Marriott points, you're looking at 0.8-0.9 CPP. Marriott's 5th night free benefit helps: a 5-night stay at 79,400 costs 317,600 points (4 x 79,400), dropping effective per-night cost to 63,520 points.
Transfer path: Chase UR -> Marriott at 1:1, or Amex MR -> Marriott at 1:1
4. Cape Fahn Hotel (SLH/Hilton) -- 95,000 Hilton Points
Points: 95,000/night | Cash: $1,077/night | CPP: 1.1 cents
The hidden gem. Cape Fahn is a Small Luxury Hotels of the World property that joined Hilton's portfolio -- meaning you can book it with Hilton Honors points. The hotel sits on its own private island (Koh Fahn), accessible by a short boat ride from Samui's northeast coast. Every villa has a private pool and direct beach access on an island shared only with other hotel guests.
At 95,000 Hilton points for a $1,077/night private island villa, you're getting 1.1 CPP -- the second-best value on Koh Samui. Via Amex MR at 1:2 transfer, that's 47,500 Amex points per night -- effectively 2.3 CPP on your Membership Rewards. A private island for 47,500 Amex points is hard to beat anywhere in the world.
Transfer path: Amex MR -> Hilton at 1:2 (47,500 Amex MR per night)
5. InterContinental Koh Samui -- 63,000 IHG Points
Points: 63,000/night | Cash: $356/night | CPP: 0.6 cents
The InterContinental occupies a hillside overlooking Taling Ngam Bay on Samui's quieter southwest coast -- away from the Chaweng crowds. The resort is known for its dramatic sunset views, beachfront pool villas, and an excellent Thai restaurant. It's the most secluded of the five picks, which is either a pro or con depending on your travel style.
At 63,000 IHG points, the CPP is modest at 0.6 cents. But IHG's 4th night free benefit helps: 4 nights costs 189,000 points for $1,424 in value. Chase UR transfers to IHG at 1:1.
Transfer path: Chase UR -> IHG at 1:1
How to Get to Koh Samui
Samui Airport (USM) is a unique private airport operated by Bangkok Airways -- which means limited flight options and higher fares. Your best strategies:
- Bangkok Airways via BKK: The direct Bangkok-Samui flight takes ~1 hour. Cash tickets run $100-200 each way. This is usually cheaper than using miles for this short hop.
- Budget alternative: Fly into Surat Thani (URT) on AirAsia or Nok Air, then take the ferry combo ($15-20 total). Takes longer but saves significantly.
- Use miles for the long-haul: Book business class to Bangkok with Singapore Airlines KrisFlyer, ANA Mileage Club, or United MileagePlus (all transfer from Chase UR or Amex MR). Then buy the short Bangkok Airways hop separately.
Bottom Line
Koh Samui's 4-program mix gives points travelers real flexibility. The Hyatt Regency at 20,000 points delivers the best straight CPP value (1.4 cents) and is the clear pick for Chase UR holders. But the Hilton properties -- Conrad and Cape Fahn -- offer some of the most compelling luxury redemptions in Southeast Asia when you factor in the Amex MR 1:2 transfer ratio.
If you have Chase UR, go Hyatt. If you have Amex MR, the Conrad (private pool villa for 55,000 Amex points) or Cape Fahn (private island for 47,500 Amex points) are the kind of redemptions that make the points hobby worth it.
