JW Marriott Costa Elena Resort and Spa is set to open September 10, 2026, in Guanacaste as the first JW Marriott-branded all-inclusive resort, giving Costa Rica planners a new Bonvoy-linked luxury AI option on the northwest coast.
If you are comparing Guanacaste all-inclusives for fall or winter travel, the traveler decision is whether a first-of-brand JW all-inclusive at the reworked Dreams Las Mareas site fits better than other Costa Rica AI resorts already on your shortlist.
- Open date: September 10, 2026, per Marriott property messaging and trade reporting.
- What is new: The first JW Marriott all-inclusive resort brand product.
- Location: Guanacaste, Costa Rica, on the northwest coast.
- Inventory: About 415 rooms, including a Griffin Club hotel-within-a-hotel zone.
- Action: Check live Bonvoy and cash availability before locking nonrefundable air into Liberia.
What is opening on the Costa Elena site
The Points Guy reported that the resort is now taking reservations and is scheduled to open September 10 as JW Marriott’s first all-inclusive property in Guanacaste.
Rather than a pure ground-up build, developers reimagined the former Dreams Las Mareas Costa Rica site. That conversion matters for travelers who already know the Mareas coastline and want to understand what brand and product change sits on familiar ground.
TPG cites about 415 rooms, a Griffin Club hotel-within-a-hotel with butler service and dedicated pool and beach access, a 44,000 square foot poolscape marketed as Costa Rica’s largest resort poolscape, and a 16,000 square foot Spa by JW.
Food and drink are positioned as a full all-inclusive set with 11 bars and restaurants spanning buffet, Japanese, seafood, Italian, and Costa Rican concepts, plus a culinary school. The property also plans a stand-alone root beer stand as a brand heritage nod.
Families get a kids club and Family by JW experiences in the reported program mix. Couples and privacy seekers should pay more attention to Griffin Club access rules and whether those rooms are required for the quieter beach and pool zones.
How this changes a Guanacaste shortlist
A JW Marriott all-inclusive is not only another beach resort. It is a Bonvoy-linked brand entry into a segment that often forces travelers to leave points ecosystems for pure AI specialists. That linkage can change the shortlist for cardholders who already think in free nights and elite night credits. It does not automatically make JW the best beach product for every party size.
That can matter for U.S. travelers sitting on Marriott free night certificates or Bonvoy points who still want an all-inclusive beach week. Availability and award pricing can lag the cash calendar, so points travelers should recheck the live Bonvoy path rather than assume every opening-week night is redeemable.
Deep Arrival’s Costa Rica all-inclusive resorts guide remains the practical comparison layer for deciding whether a Guanacaste JW product beats other AI options on food style, transfer time, and family fit.
Guanacaste arrivals usually route through Liberia Daniel Oduber Quirós International Airport. Factor transfer time, rainy season road conditions, and any car rental plan before treating a September opening as an easy same-day beach landing.
What is confirmed versus still fluid
Forbes coverage has also framed the property as the world’s first JW Marriott all-inclusive in Costa Elena. Confirmed in independent reporting: the September 10 opening date messaging, first JW Marriott all-inclusive branding, Guanacaste location, former Dreams Las Mareas site conversion, roughly 415 rooms, Griffin Club concept, large poolscape and spa footprints, and multi-outlet all-inclusive dining.
Still fluid until you book: exact opening-week inventory, award availability, rate inclusions by package, and whether every restaurant and Griffin Club amenity is live on day one.
TPG noted earlier that Marriott’s booking calendar could show later start dates than the stated open date and that award rates were not yet available in that snapshot. Treat any old calendar screenshot as stale and reprice on the current Marriott page.
The official Marriott property page remains the primary booking authority even when bot blocks make automated scrapes fail. Use trade reporting for context, then confirm rates and inclusions on the JW Marriott Costa Elena Marriott page in a logged-in Bonvoy session before paying air deposits.
Who should book now versus wait
Book now if your travel window is fixed around mid-September through peak winter and you need a named brand all-inclusive with Bonvoy connectivity. Early inventory on a first-of-brand opening can thin once social proof and elite chatter build. Waiting can still pay if you need more dining proof after open. The tradeoff is simple: certainty of dates versus certainty of product polish.
Wait if your trip is flexible and you want first-month operational reviews of dining, Griffin Club delivery, and spa access. A brand opening can still change restaurant hours and room product readiness after the ribbon cutting.
Families should confirm kids club ages and Family by JW inclusions against their children’s ages before choosing this over a proven family AI with more third-party reviews.
Points optimizers should model both cash and certificate scenarios. A free night certificate on a high cash rate can outperform a cheaper non-Bonvoy AI even when the all-inclusive premium looks steep.
What to verify before you buy flights
Confirm the room category and whether Griffin Club access is required for the beach or pool privacy you expect. Marketing language about dedicated areas can still mean an upsell path rather than a standard room benefit.
Next, price the all-inclusive inclusions against what you will actually use. Eleven restaurants only help if hours and dress codes fit your group, and a large spa only helps if appointments are available during your short stay.
Then check cancellation and deposit rules on the Marriott booking path. Opening-month inventory can be more restrictive once demand rises, especially around U.S. holiday weeks.
Finally, map Liberia arrival times against check-in. A late evening flight can force a night in Liberia or a dark transfer, which changes the value of a day-one beach plan.
| If you… | What to do |
|---|---|
| Want the first JW all-inclusive | Price September 10 onward stays on Marriott and compare against other Guanacaste AI resorts. |
| Travel on Bonvoy points or certificates | Recheck live award inventory; early reports showed award gaps after cash dates appeared. |
| Need quiet privacy | Compare Griffin Club rooms and access rules against standard wings before booking. |
| Are flying into Liberia | Add transfer time and seasonal road conditions to the resort choice, not only beach photos. |
| Can wait for reviews | Hold nonrefundable air until first-month dining and amenity delivery reports appear. |
- Open date: Treat September 10, 2026, as the advertised start and reconfirm on Marriott before travel.
- Brand first: This is JW’s first all-inclusive, not a small room renovation story.
- Compare AI peers: Use Costa Rica all-inclusive shortlists before assuming JW is automatic.
- Points path: Verify Bonvoy cash and award calendars separately.
- Arrival plan: Build Liberia transfer time into same-day check-in expectations.
The practical headline is that Guanacaste is gaining a first-of-brand JW Marriott all-inclusive on a known beach footprint, and travelers who care about Bonvoy and brand standards now have a concrete September date to price against other Costa Rica AI options.
