Planning a holiday for two adults and two kids is a very specific puzzle. You're not just booking travel — you're negotiating between what a 5-year-old needs (short walks, afternoon naps, pools), what an 8-year-old wants (activities, excitement, something to talk about at school), and what parents actually need (a budget that doesn't hurt, accommodation that doesn't feel like a compromise, and at least one dinner where everyone sits down).
Most trip planners treat your family like four generic travelers. They don't know your kids' ages. They don't adjust pacing. They don't flag that a 6-hour road day with a 5-year-old is a very different experience than a 6-hour road day alone.
This is the itinerary that Famila.Travel generated for a real test: an 8-day trip to Portugal for 2 adults, one child aged 5, one child aged 8, flying from London, with a €3,500 total budget.

The trip: Lisbon & Cascais, Portugal — 8 days
Trip profile
Family: 2 adults, 1 child aged 5, 1 child aged 8
Departure: London
Dates: 25 June – 2 July 2026 (8 days, 7 nights)
Budget: €3,500 total
Travel style: Relaxed, mix of culture and beach, with hiking and cycling
The plan overview — route, dates, travelers, budget, and a separate weather forecast for Lisbon and Cascais.
Flights
Outbound: London → Lisbon (LIS). TAP Air Portugal, direct, around 3.5 hours. Estimated: €502 for 4 passengers.
Return: Lisbon → London. Estimated: €604 for 4 passengers. Total flight cost: €1,106.
AI note: direct flights are strongly recommended with a 5-year-old. Connections add risk of delays and meltdowns in unfamiliar airports.
Accommodation
Nights 1–3: Lisbon — Memória Alfama Hotel
Family rooms with rooftop views in the historic Alfama district. Estimated: €480–€600 total for 3 nights.
Why Alfama: walking distance to Castelo de São Jorge and the Tram 28 route, with quieter streets at night than the Baixa/Chiado tourist core. Good base for the city's most kid-friendly viewpoints.
Nights 4–7: Cascais — Hotel Cascais Miragem
Beachfront, family suites, pools. Estimated: €520–€680 total for 4 nights.
Why Cascais second: easier pace for the back half of the trip. Beach town, calm sea, great for young kids. 40 minutes from Lisbon by train — scenic and cheap (€2.30 per person each way).
Accommodation specificity — hotels named, priced and linked directly to booking.com, not just "look for a family hotel."
Day-by-day itinerary
Day 1 — Arrival in Lisbon (25 June)
Morning: Fly London → Lisbon. Arrive at Humberto Delgado Airport, collect rental car, drive to Memória Alfama Hotel.
Afternoon: Easy walk around Belém — low effort, river views, kids can run around. Nap window built in, 1–3pm.
Evening: Pastéis de Nata tasting at Pastéis de Belém (the original, since 1837). Family-friendly dinner near the hotel.
Pace note: resist the urge to cram sightseeing into arrival day. A relaxed start sets a better tone for the whole trip.
Day 2 — Historic Lisbon & viewpoints (26 June)
Morning: Classic Tram 28 ride through the historic neighbourhoods. Get on early to avoid queues. Get off at Miradouro da Graça for the view.
Late morning: Castelo de São Jorge — panoramic views over the city, plenty of space for kids to roam, peacocks in the grounds.
Afternoon: Alfama neighbourhood walk — narrow streets, fado music, street art. 90 minutes is plenty with young kids.
Evening: Riverfront dinner. Budget €45–€55 for the family.
Day 3 — Lisbon → Cascais (27 June)
Morning: Final Lisbon morning. LX Factory if it's a weekend — repurposed industrial space with food, shops and a kid-friendly atmosphere. Otherwise the Maritime Museum.
Afternoon: Check out, drive (or train from Cais do Sodré, 40 minutes, €2.30 per person) to Cascais. Settle into Hotel Cascais Miragem and head straight to the beach.
Evening: Dinner in Cascais town centre. Lively, family-friendly, good seafood. Budget €50.
Day 4 — Sintra day trip (28 June)
Morning: Train from Cascais to Sintra (~40 minutes). Go early — Sintra is crowded by midday in summer.
Morning activity:Pena Palace — the colourful fairy-tale exterior is the main event. The 8-year-old will love the battlements; the 5-year-old will love the colours. Allow 2–2.5 hours.
Lunch: Pack a picnic or eat at one of the cafés in the palace grounds — town centre restaurants get rammed.
Afternoon: Brief walk through Sintra village, train back to Cascais by 3pm. Avoid the worst of the heat.
Evening: Low-key dinner near the hotel. Early night.
AI note: Sintra with young kids works best as a half-day. Full days end in tired, overwhelmed children and frustrated parents.
Day 5 — Cascais beach & town (29 June)
Morning: Praia da Rainha — calm, shallow, very safe for young children. The decompression morning.
Afternoon: Cascais old town wander, market square, ice cream on the seafront.
Evening: Sunset dinner with the kids running on the beach. Bedtime on time.
Day 6 — Guincho & Oitavos Dunes (30 June)
Morning: Taxi or Uber to Guincho Beach (15 minutes, ~€12). Dramatic Atlantic beach, big waves — older kids love it, younger kids may find it rough. AI flags this; check conditions first.
Afternoon: Coastal hiking through the Oitavos Dunes nature reserve and back toward Cascais via Boca do Inferno (the "Mouth of Hell" — a dramatic sea cave). 8-year-olds rate it excellent.
Evening: Dinner in Cascais, ice cream on the seafront. Light-rain day in the forecast — pack a jacket.
Day 7 — Last full day in Cascais (1 July)
Morning: Bike rental — Cascais has flat, family-friendly coastal cycling paths. The 5-year-old goes in a child seat; the 8-year-old gets their own bike.
Afternoon: Last beach session. Read, swim, do nothing.
Evening: Final family dinner. Order the cataplana.
Day 8 — Departure (2 July)
Morning: Leisurely breakfast. Last walk along the seafront.
Afternoon: Drive (or train + transfer) back to Lisbon airport. Allow 2.5 hours before departure with kids.
Evening: Fly home.
Each day with timed activities, meal notes, pro tips and a built-in nap window — calibrated to the kids' ages.

What the AI got right
A few things stand out in how this itinerary was built differently from a generic planner.
Age awareness. The Sintra recommendation comes with a specific note about half-day visits with young kids. Guincho Beach is flagged as potentially too rough for a 5-year-old. The schedule has a built-in nap window on Day 1. These aren't generic travel tips — they're calibrated to the specific ages entered (5 and 8).
Pacing. No day has more than two major sightseeing stops. Afternoons are consistently lighter than mornings. There's a deliberate decompression structure: hard sightseeing front-loaded in Lisbon, then a slower beach-and-bike second half in Cascais.
Specific recommendations. Not "find a custard tart shop" — Pastéis de Belém, since 1837. Not "look for a family hotel" — Memória Alfama in the historic district, €480–600 for 3 nights, with rooftop views. The level of specificity is what makes the plan actually usable.
Per-city weather. The weather forecast splits between Lisbon and Cascais — small thing, but those forecasts diverge by a few degrees in June, and Cascais gets more Atlantic wind. A generic planner wouldn't bother.
Practical logistics. The train from Lisbon to Cascais is suggested over keeping the rental car for the second half — cheaper, scenic and avoids parking stress. A 5- and 8-year-old on a train is manageable; the same family parking in Cascais is less fun.
After the plan — a dashboard with flight-delay protection, trip-email reminders, and a saved family profile the AI uses on the next trip.
Try it for your family
This itinerary took about 90 seconds to generate on Famila.Travel. The inputs were simple: destination, dates, 2 adults + 2 kids with ages, budget, travel style.
The inputs — family composition, home city, travel interests. The AI builds the plan around these, not around a generic traveler.
The output isn't a list of generic recommendations. It's a plan that accounts for who's actually travelling — including the 5-year-old who needs an afternoon nap and the 8-year-old who wants to feel like an explorer.
