Maui’s Longest Waterslide Is at Wailea Beach Resort — Marriott

At 325 feet, the waterslide at the NALU Adventure Pool is the longest on Maui — and for families with elementary-age kids, that single fact tends to settle the booking conversation. Wailea Beach Resort – Marriott earns its Family Preferred rating on the strength of a genuinely well-designed pool complex, a structured kids club, and direct proximity to two of Wailea’s best beaches. The honest caveat: this is a premium-priced, non-all-inclusive resort with a resort fee and parking charged on top of already high room rates, so food, drink, and activity costs can accumulate quickly.

The NALU Adventure Pool: Why It Draws Families Back

The pool complex is the resort’s clearest family differentiator. The NALU Adventure Pool features a zero-entry section with animal sculptures and a shallow splash area that works well for toddlers and younger children, while the 325-foot slide handles the older kids. Having both in the same space means parents of mixed-age groups aren’t split across different areas of the resort. There’s also a separate adult pool for parents who want time away from the main family hub, and a hot tub.

Away from the pools, the free Game Space gives older children and teenagers a legitimate indoor option — arcade games, billiards, foosball, and shuffleboard — while the on-site Movie House with beanbag seating provides a low-effort evening activity that doesn’t require anyone to leave the property.

A Kids Club That Covers the Core School-Age Years

The Keiki Kids Club takes children aged 5 to 12, which covers the full elementary-age window that this resort is best suited for. The resort also runs Hawaiian cultural programming — ukulele lessons and cultural activities are offered on-site, which gives families a way to engage with the destination beyond the pool. Teenagers are catered to more broadly through the activity spaces and beach access rather than a dedicated teens club, which is worth factoring in if you’re travelling with children above age 12 who need structured programming.

Beach Access and Getting Out on the Water

The resort sits directly alongside Wailea Beach and is adjacent to Ulua Beach — both are among the calmer, more swimmable stretches on Maui’s south shore, and both are practical for snorkeling. Note that the resort’s beach access is immediate in terms of distance, but a dedicated step-from-resort-to-sand setup is not available; the beaches are moments away rather than at the foot of the property.

On-site snorkeling and scuba are offered, and bicycle rental is available for families who want to explore the Wailea coastal path. For activities off the resort — surf lessons, boat tours, guided snorkel excursions — booking ahead is recommended given demand in peak season. You can browse family-friendly tours and activities or compare kid-friendly day tours before you arrive to secure spots.

Location and Getting Around

The resort is at 3700 Wailea Alanui Dr, Wailea — on Maui’s south shore, about 30 minutes from Kahului Airport under normal traffic conditions. The Shops at Wailea are a 5–10 minute walk, which gives families a realistic option for dining outside the resort and helps manage costs. Grocery is available nearby, which is worth knowing given that food and drink within the resort runs expensive. Maluaka Beach (known for sea turtle sightings) is a 10–15 minute drive. Haleakala National Park’s summit is around 90 minutes away — a viable day trip for families with older children but a full commitment. Get directions to the resort.

What Recent Guests Say

• Several recent reviewers praise the staff as friendly and attentive, with many noting that team members went out of their way to assist guests throughout their stay.
• The pools — particularly the infinity pool and adult pool area — are a consistent highlight mentioned across multiple reviews, with families also appreciating the kids’ water slides and amenities.
• A common theme in guest feedback is that the resort’s location is excellent, with easy walking access to nearby beaches, shops, and restaurants along the Wailea path.
• Some guests raise concerns about room quality and maintenance, noting issues such as outdated furnishings, malfunctioning fixtures, or inconsistent housekeeping service.
• Several reviewers mention that the resort feels expensive relative to what is delivered, with a few noting that certain amenities or service standards did not fully match the premium price point.

Who This Hotel Suits — and Who Might Want to Look Elsewhere

This resort is a strong fit for families with children roughly aged 5 to 12 who will use the pool complex heavily and benefit from the Keiki Kids Club. The combination of active water amenities, beach proximity, and the Game Space also keeps teenagers reasonably engaged. Parents who want adult time have a separate pool and a full spa.

Families on a tighter budget should weigh the numbers carefully. Room rates start around $800 per night for a family of four in peak season, with resort fees and parking additional. Food and drink on-site are expensive by multiple guest accounts, and the Shops at Wailea — walkable, but not cheap — represent the main nearby alternative. Families expecting everything to be included for that price point will find this model doesn’t work that way.

Families with children under 5 will find the zero-entry splash area usable, but the resort’s strongest offering skews older. Those travelling primarily with teenagers aged 13 and above should note there is no dedicated teens club; the activity spaces serve that age group informally rather than through structured programming. And if room condition consistency matters to you, the mixed guest feedback on maintenance is worth factoring in.
