The honest review
Beaches Turks & Caicos is the only resort in this analysis with a 98 in Kid Amenities, and it earns it. The Pirates Island Waterpark is 45,000 square feet of engineered chaos: 9 slides at different intensity levels (including a 4-story dueling racer for tweens+), a lazy river that loops the property, a Surf Stream artificial wave for boogie boarders, and three separate splash zones segregated by age.
The Sesame Street partnership is the family-travel underrated gem. Big Bird, Elmo, Cookie Monster, and Abby Cadabby live on property and rotate through scheduled meet-and-greets, story times, character breakfasts (book the Beaches Beach Breakfast — it's the highlight for kids 2-7), and pool-side appearances. The kids age out around 8 but for ages 2-7 it's transformative.
For babies and toddlers: the included baby concierge service is genuinely differentiated. They prep bottles, supply Pampers diapers and Johnson's products, deliver baby food, and provide cribs/strollers/monitors at no charge. Camp Sesame (ages 0-5) runs daily and accepts babies as young as a few weeks old with parent presence — most all-inclusives start at age 3-4.
For teens: the Liquid Teen Club is a dedicated 10pm-3am dance/lounge space with mocktail bar, X-Box, foosball, and supervision. Teens disappear into it and you don't see them until breakfast — exactly what you want from this property.
Grace Bay is consistently rated the world's #1 beach (Tripadvisor, multiple years). It's a 3-mile stretch of powder-white sand and shallow turquoise water that runs in front of all the resort villages. The water stays under chest-deep for 50+ yards offshore — the safest beach swimming for kids you'll find at a Caribbean all-inclusive.
Where it loses points: pricing in peak season is north of $1,200/night for the family-of-4 package. The property is huge (75 acres, 4 distinct villages) and walking between things gets exhausting with little kids — trams run but the wait can be 10+ minutes. Food quality varies wildly by restaurant — Sky (Italian) and Bayside (seafood) are excellent; the buffets are mediocre.
