Every points blog tells you the best redemptions. Nobody tells you the worst ones.
We ran the numbers across official hotel websites for island hotels and found something the "best hotel on points" guides never mention: at many properties, you're better off paying cash. When Hilton charges 119,000 points for a $331 room, or Marriott wants 120,000 points for a $477 all-inclusive, you're destroying value -- burning points worth more elsewhere.
Here are three islands where the points math goes sideways, with the traps to avoid and the sweet spots to target instead. All pricing based on rates shown on official hotel websites as of March 26, 2026.
Santorini: Same Island, 7x Value Difference
Santorini has the widest CPP gap of any island we reviewed. Two hotels on the same island deliver wildly different value per point.
The Trap: Aressana Spa Hotel (SLH/Hilton) -- 119,000 Hilton Points, $331 Cash
CPP: 0.3 cents. This is one of the worst points redemptions on any island, period. You're burning 119,000 Hilton Honors points for a $331 room. If you transferred ~59,500 Amex MR to get those Hilton points (at 1:2), you've effectively spent over $1,000 worth of flexible points on a $331 room. You literally lost money.
Pay cash. Put the $331 on a credit card, earn points on the purchase, and save those Hilton points for a property where they deliver at least 0.5 CPP -- the widely accepted floor for a worthwhile Hilton redemption.
The Trap: Domes Novos Santorini (Marriott Autograph) -- 82,000 Marriott Points, $497 Cash
CPP: 0.6 cents. Below Marriott's "worth it" threshold of 0.7 CPP, and it costs 22,000 more points than the best option on the island.
The Sweet Spot: Canaves Oia Suites (Marriott) -- 60,000 Points, $1,200 Cash
CPP: 2.0 cents. Fewer points than Domes Novos (60K vs 82K), but the cash rate is $1,200 instead of $497. That's 3.3x more value per point for fewer points. Same island, same program -- completely different outcome.
The lesson: On Santorini, only Canaves Oia and Santo Maris Oia (50,000 pts, $800, 1.6 CPP) justify using Marriott points. Everything else is a cash play.
St. Lucia: The 4.5x Points Penalty
St. Lucia shows what happens when multiple programs compete on the same island with vastly different pricing models.
The Trap: Harbor Club (Hilton Curio Collection) -- 79,000 Hilton Points, $252 Cash
CPP: 0.3 cents. Harbor Club is a nice boutique hotel in Rodney Bay with a rooftop pool. It's also a terrible points redemption. At 79,000 Hilton points for $252, you're getting well below the average Hilton redemption value (0.5c). Pay the $252 in cash. Use those 79,000 Hilton points at a property where they're worth 2-3x more.
The Trap: Royalton Hideaway St. Lucia (Marriott Autograph) -- 120,000 Marriott Points, $477 Cash
CPP: 0.4 cents. Here's where the math gets painful. This adults-only all-inclusive costs 120,000 Marriott points for $477/night. Meanwhile, Secrets St. Lucia charges 27,000 Hyatt points for $978/night -- a much higher-end all-inclusive, at 4.5x fewer points. You're paying a massive "Marriott tax" for a worse deal.
The Sweet Spot: Secrets St. Lucia (Hyatt) -- 27,000 Points, $978 Cash
CPP: 3.7 cents. All-inclusive -- meals, drinks, activities included. With Hyatt's 5th night free, a 5-night stay costs ~108,000 points for $4,890 in value (4.5 CPP effective). This is one of the best redemptions in our entire database.
The lesson: St. Lucia is a one-program island. Hyatt crushes everything else by a factor of nearly 10x on CPP. If you don't have Chase UR to transfer to Hyatt, pay cash.
Koh Samui: Budget Hotels That Eat Your Points
Koh Samui has 13 points hotels we reviewed, but the bottom of the list is a graveyard of bad redemptions -- and even the luxury Hilton properties disappoint.
The Trap: Wyndham Garden Samui Wing -- 15,000 Wyndham Points, $67 Cash
CPP: 0.4 cents. Fifteen thousand Wyndham points for a $67 room. Those same 15,000 Wyndham points book a $250+ room at many other Wyndham properties. And $67/night? That's a credit card purchase, not a points redemption.
The Trap: Holiday Inn Resort Koh Samui (IHG) -- 32,000 IHG Points, $156 Cash
CPP: 0.5 cents. Same story. 32,000 IHG points for a $156 room -- right at the floor of IHG's "worth it" threshold. Sub-$200 rooms are almost never worth redeeming points for.
The Surprise: Even Luxury Hilton Properties Disappoint
Conrad Koh Samui demands 218,000 Hilton points for a $670 room (0.4 CPP). Cape Fahn, an SLH property, costs 258,000 points for a $1,082 room (0.8 CPP). Neither clears the 1.0 CPP bar you'd want for burning that many Hilton points.
The Sweet Spot: Hyatt Regency Koh Samui -- 18,000 Points, $208 Cash
CPP: 1.2 cents. Only 3,000 more Hyatt points than the Wyndham costs in Wyndham points, but the room is worth 3x more. At 1.2 CPP, your Chase UR points are working efficiently.
The lesson: On Koh Samui, the Hyatt Regency is the only redemption that clearly delivers value. Everything else -- including the luxury Hilton properties -- falls below worthwhile thresholds. If you're eyeing the Conrad or Cape Fahn, pay cash and save your Hilton points for a property with better CPP.
The Universal Rule: When to Pay Cash
After analyzing every island we reviewed, one pattern is consistent:
Pay cash when the room costs under $300/night. Below that threshold, CPP values almost always drop below the "worth it" line for every program:
| Program | "Worth It" CPP Floor | Typical Cash Rate Where It Works |
|---|---|---|
| Hyatt | Above 1.0c | $250+ rooms |
| Marriott | Above 0.7c | $400+ rooms |
| Hilton | Above 0.5c | $350+ rooms |
| IHG | Above 0.5c | $300+ rooms |
The expensive resorts ($500+/night) are where points shine. The mid-range hotels ($150-300) are where points get destroyed.
Bottom Line
Not every "free night" is free. When you burn 119,000 Hilton points on a $331 room, you're paying an invisible cost -- the value those points could have delivered at a better property.
Before you redeem, check the CPP. Divide the cash rate by the points cost. If it's below the thresholds above, pull out your credit card and save those points for a redemption that actually delivers.
Your points are a currency. Don't spend $100 bills on $30 purchases.
