Headline Comparison Table

Destination	Flight time (non-stop)	Non-stop carriers DFW	Est. flights (family of 4)	Est. lodging 6 nights (suite, separate bedroom)	Est. total trip cost	Sargassum/weather risk	Beach swimmable for 1yo?
Riviera Maya / Cancun	~2h 30m	AA, Southwest (DAL), Spirit, Frontier	$1,200–$ 1,800	$3,500–$ 8,500 (AI, varies by resort)	$4,700–$ 10,300	Heavy sargassum risk (2026 is near-record year), heat/humidity high, hurricane low	Yes at sheltered bays (Maroma, Puerto Morelos, Akumal); avoid east-facing
Los Cabos	~3h	American only	$1,700–$ 2,400	$3,800–$ 9,000 (AI, varies by resort)	$5,500–$ 11,400	Very hot/dry, sea warm (80–83°F), occasional brief afternoon storms, hurricane risk rises in Aug	Mixed — most Cabo beaches NOT swimmable. Must pick resort on swimmable beach (Palmilla, Chileno, Medano, Cabo Real).
Turks & Caicos (Provo)	~3h 45m–3h 55m	American Saturday only	$2,400–$ 3,400	$4,000–$ 16,000 (huge range by resort)	$6,400–$ 19,400	Trade winds keep heat tolerable, low hurricane risk in late July, far less sargassum than Mexico	Yes — Grace Bay is world-class for toddlers (calm, reef-protected, shallow).

Flight Reality Check (Big One for Turks & Caicos)

Cancun (CUN): Easy. 8–12 non-stop departures/day from DFW/DAL. Either date window works perfectly. AA, Southwest from DAL (lap infant free + 2 free bags is a real win), Spirit cheap-but-stripped.

Los Cabos (SJD): AA monopoly on non-stops from DFW (2–3/day). Either window works. ~ $50–$ 80/adult cheaper in Window B.

Providenciales (PLS): ⚠️ Problem. AA's DFW→PLS non-stop is Saturday-only seasonal.

Window A (Mon Jul 20 – Mon Jul 27): no non-stop matches.
Window B (Thu Jul 30 – Thu Aug 6): no non-stop matches.
Workarounds:
- Shift dates to Sat Jul 18 – Sat Jul 25, Sat Jul 25 – Sat Aug 1, or Sat Aug 1 – Sat Aug 8 to ride the non-stop.
- Otherwise, 1-stop routing through MIA or CLT = 6–9 total travel hours, exceeds your 4-hour rule by a wide margin.
- The return non-stop is ~4h 05m–4h 15m — slightly over your 4-hour cap even on the good day.

Window B is consistently $200–$ 500 cheaper across destinations and resorts — slightly softer demand once early-August school-start dates approach.

Recommendation

Top pick: Azul Beach Resort Riviera Maya by Karisma, Window B (7/30–8/6).

Why:

Genuinely engineered for babies. Gerber baby food in every restaurant, sterilizers, bottle warmers, cribs, strollers, baby monitors — all included. Family Swim-Up Suite is exactly the "separated bedroom" you asked for, and the kids can swim from the suite into a shared pool channel.
Easiest logistics. 2h 30m non-stop from DFW, ~ $1,200–$ 1,800 in flights, no Saturday-departure constraint, passport-only entry.
Cost-controlled. ~ $6,500–$ 8,200 estimated trip total — middle of the road, with the highest baby/toddler value-per-dollar of any option.

Honorable mentions:

Beaches Turks & Caicos if budget isn't the constraint and you'd shift your dates to Sat–Sat to get the non-stop. The 0–24mo nursery is unique in the Caribbean and gives you actual parent-time on vacation. Plan on $15k–$ 20k total all-in.
Hyatt Ziva Cancun as a more conservative pick — slightly less baby-tailored than Azul, but cheaper, more familiar brand, and Camp Hyatt is solid for the 4yo.

To avoid:

Turks & Caicos on your current dates — the non-stop flight constraint disqualifies it unless you shift to a Saturday cadence.
Hyatt Ziva Los Cabos — gorgeous resort but beach un-swimmable; with a 1yo the pool-only constraint is a real downside.

Sargassum (Mexico-specific) — Worth Reading

USF's 2026 sargassum outlook projects this as a near-record year. Peaks across the Riviera Maya in July, easing slightly in August. East-facing beaches (Tulum, Playa del Carmen open coast) hit hardest. Mitigations:

Pick a sheltered/protected beach: Maroma (Mayakoba area), Puerto Morelos reef-protected, north-facing Cancun Hotel Zone, Akumal cove. Azul Beach RM is in Puerto Morelos = reef-protected.
Resorts with daily beach-raking and offshore booms (Moon Palace, Grand Velas, Hyatt Ziva, Karisma) keep their beaches cleaner than open public stretches.
Pools are not affected. Worst case, you swim in the pool and walk past raked seaweed to the beach.

Turks & Caicos faces almost none of this — Grace Bay sits outside the main Sargasso belt.

Passport & Entry

All four family members need valid US passports for any of these destinations. Apply now if anyone (especially the 1yo) doesn't have one — current routine processing is 4–6 weeks (2–3 weeks expedited).
Mexico: digital FMM tourist card included with airline ticket; no advance form.
Turks & Caicos: digital "TCI Travel Authorization" required pre-flight (free, ~10 min/traveler).

Next Steps

Decide: destination + window (my recommendation: Azul Beach RM, Window B).
Verify live pricing via:
- Costco Travel (often best bundled rate; flights + resort packaged)
- Apple Vacations or CheapCaribbean (similar bundling)
- Resort direct (sometimes matches; check loyalty perks if you have Hyatt status, AmEx FHR, etc.)
Book travel insurance with a hurricane/CFAR rider — late July is historically quiet but it's still hurricane season.
If choosing T&C: decide whether to shift dates to Sat–Sat for the non-stop, or accept 1-stop routing.
