Wai Kai

What Wai Kai does

Wai Kai (legally "The LineUp at Wai Kai") is a privately held, 52-acre water sports and lifestyle destination located at 91-1621 Keoneula Blvd in Ewa Beach, West Oahu, Hawaii, founded in 2023 and developed by Haseko within the Hoakalei Resort master-planned community. The facility combines three core experience pillars: a 100-foot-wide citywave-powered standing wave surf park (with 30ft, 65ft, and 100ft channel settings), a 52-acre naturally filtered inland saltwater lagoon for kayaking, paddleboarding, hydro bikes, and outrigger canoeing, and a 1+ acre AquaVenture floating obstacle course (with a Keiki track for ages 4-6 and Aloha track for ages 7+), to be expanded in 2026 with the elevated AquaPeakz course and 20-foot slide tower.

The company monetizes through six revenue streams: per-activity tickets and bundled packages (ranging from $15-$249 across kids' passes, single sessions, multi-activity bundles, and the $124.99 four-activity bundle), food and beverage across five on-site venues (The LookOut, FOAM Coffee & Bar, The WaveBar, Hali'a by Side Street Inn, Sidewalk Cafe), venue and cabana rentals ($150-$200 for 4 hours or full day), retail (Sessions shop, MiiR reusable products), monthly/6-month memberships from $50/month with Nalo Kai VIP lounge access, and shuttle services ($35 roundtrip) connecting Waikiki and Ko Olina to the site. Distribution is predominantly direct-to-consumer via the waikai.com website with FareHarbor booking integration, supplemented by a dedicated Japanese-language site (jp.waikai.com) operated with booking partner NutmegLabs.

The customer base spans Oahu tourists (mainland US and inbound Japanese), Hawaii kamaaina residents accessing membership and event programming, multi-generational families with children, and secondary segments including corporate groups, schools, and community organizations served through venue rentals and a fundraising program. The business uses event-driven demand generation through weekly signature programming (Thursday Night Market with 50+ vendors, LineUp Surf Show, Trivia Tuesday Tournament) and has earned recognition including USA Today #4 Best New Attraction 2024, Best of HONOLULU Family 2024, and Hawaii's Best 2025. No public revenue disclosures, headcount data, or independent investor information are available; the company is operated as a private venture under Haseko ownership.

Broad incumbents

• Aquatica (SeaWorld): Chain of SeaWorld-operated water parks offering multi-attraction day passes, cabanas, and dining. Provides a benchmark for unit economics, F&B attachment, and seasonal pass/membership design at destination-scale.
• Atlantis Aquaventure (Dubai): One of the world's largest water park destinations. Benchmarks scale, multi-attraction ticketing, integrated F&B, and resort-destination economics that Wai Kai aspires to at a smaller footprint.
• Disney's Typhoon Lagoon: Florida water theme park with a signature wave pool, multi-attraction ticketing, and integrated F&B. Comparable on operations, family segmentation, and bundling — though at much larger scale and brand recognition.
• Schlitterbahn (Cedar Fair): Historic Texas-based water park brand with river-style lazy attractions and resort lodging. Comparable on destination-resort positioning combining water-based recreation with lodging and multi-day ticket economics.
• Siam Park (Tenerife): Repeatedly rated among the world's best water parks, featuring a wave pool plus slide and lazy-river attractions. Comparable as a destination water park that integrates food, retail, and event programming at premium ticket pricing.

Direct peers

• BSR Cable Park & Surf Resort: Texas-based surf park and water sports resort using standing-wave technology. Comparable as an inland destination combining man-made surfing with hospitality, food, and lodging.
• Surf Snowdonia: A UK inland surf lagoon using man-made wave technology. Closest concept-comparable to Wai Kai's citywave standing wave — proof point for the inland-surf business model with adjacent food and accommodation.
• Wet'n'Wild Hawaii: Hawaii's other major water park, located in Kapolei near Wai Kai. Directly comparable as a Hawaii-based water-based attraction serving tourists and residents with day-pass admission, food, and group events.

Others

• Wavegarden: Spanish manufacturer and operator of man-made wave technology — the principal global alternative to citywave. Serves as both a comparator on technology choice and a potential alternative supplier/competitor for new inland surf installations worldwide.

Regional players

• Hilton Waikoloa Village: Large Hawaii resort with multiple pools, saltwater lagoon, and water-based activities. Comparable as a Hawaii destination bundling lodging-adjacent water recreation and F&B, competing for the same tourist discretionary spend — though it is lodging-led rather than activity-led.
