Three days in London gives you enough time to hit the iconic landmarks, do one major paid experience, and leave room for the city to surprise you. Here's a practical day-by-day plan that balances free museums, must-do experiences, and some breathing room — because rushing kids through London doesn't work.
Estimated total activity cost for 3 days, family of 4: USD 500–750 (depending on which paid experiences you choose)
---
Day 1: Central London Icons
Morning
Start with London Sightseeing Tours — USD 100–150 for a family day ticket. The hop-on/hop-off double-decker is the best orientation tool in the city. Sit on the top deck at the front and watch the city scroll past. It covers Big Ben, the Houses of Parliament, Buckingham Palace, the Tower of London, and Tower Bridge on a single loop. Spend the morning on the bus — use the audio guide to give context, and let kids spot the landmarks they recognize.
Pro tip: Download the operator's app before you leave — live bus tracking helps you plan stops and reduces waiting times.
Midday
Hop off at Trafalgar Square — Trafalgar Square is free. Climb on the lions, look up at Nelson's Column, and let the kids run around. Walk into The National Gallery (free) and pick up a family trail from the information desk. Spend 45–60 minutes finding Van Gogh's Sunflowers, the Rubens battle scenes, and whatever else catches their eye. Kids are often surprised by how physically large famous paintings actually are.
Lunch nearby at Bill's Covent Garden Restaurant — USD 64–89 for a family meal. Family-friendly, relaxed, and in one of the best areas of London to walk around after.
Afternoon
Head to Covent Garden and walk through the market. Then make your way to the South Bank — cross the Millennium Bridge on foot (free, with a great view of St Paul's Cathedral) and walk along the Thames toward the Tate Modern. The Tate Modern's permanent collection is free and the scale of the Turbine Hall is always impressive.
For dinner, try Ave Mario in Covent Garden — USD 102–140 for a family meal. Spectacular interior, proper Italian pasta, and the theatrical presentation makes every course feel like an event.
Day 1 activity cost: ~USD 200–300

Day 2: A Big Experience + Free Museums
Morning
Warner Bros. Studio Tour London — USD 160–200. This is your big paid day. You need 3–4 hours minimum for the tour — the Great Hall, the Forbidden Forest, Platform 9¾, the full-size Hogwarts model. Book this months in advance; it genuinely sells out. Eat a full breakfast before you go or bring food in — the Studio cafe prices are high.
Pro tip: The tour ends in the gift shop. Set a per-child souvenir budget before you go in, not after.
Afternoon
After the Studio Tour, head to the Natural History Museum (free). The Waterloo exit from the Studio Tour connects easily to the Tube. Even after a full morning at the Studio, the dinosaur hall can absorb another hour or two. The Science Museum is right next door if you want more — also free.
If the kids need outdoor space, walk through Kensington Gardens (free) and visit the Diana, Princess of Wales Memorial Playground inside — the pirate ship is a genuine landmark in itself.
Evening
Low-key evening. Mother Mash Carnaby — USD 51–76 for a family meal. Simple, filling, and reasonably priced for central London. Then walk through the Carnaby Street area.
Day 2 activity cost: ~USD 200–280

Day 3: East London + Something Different
Morning
StreetHunt Games — USD 50–80 per group. A phone-guided scavenger hunt through real London streets. Kids feel like they're solving an actual mystery while walking through the city. The cost is per group, not per person — one of the best value things you can do in London. Works for ages 7+ with some parental guidance for younger kids.
Alternatively, do the SANDEMANs London, Free Walking Tour — free (tip USD 10–15 per adult). Guides are selected for their energy and storytelling ability. Book online in advance even though it's free — it reserves your place.
Midday
Head to East London. Mudchute Park and Farm is free and one of the most unexpected things you can find in a major city — llamas, horses, and pigs a 10-minute Docklands Light Railway ride from Canary Wharf. Pack a picnic or use the on-site cafe (USD 15–25).
Nearby, London Museum Docklands is free and worth an hour in its historic warehouse building.
Afternoon
For something completely different, book Immersive Gamebox - Southbank — USD 100–130. A private room where the walls, floor, and ceiling all become part of an interactive game. 1–1.5 hours. Mid-week pricing is lower. Great for ages 7+.
Or if the kids prefer water, Action Watersports offers family kayaking and paddleboarding sessions on the Thames — USD 100–160. Group lessons are significantly cheaper than private. Kids come out of this one feeling genuinely capable.
Evening
End the trip at Circolo Popolare — USD 89–127 for a family meal. One of the most visually spectacular restaurants in London — every surface covered in floor-to-ceiling bottles and Italian produce. Kids are immediately fascinated by the decor before the food even arrives.
Day 3 activity cost: ~USD 150–250

Practical Planning Notes
Getting around: The Underground is the backbone of London travel. Buy an Oyster card or use a contactless bank card — it's cheaper than single tickets. Children under 11 travel free on the Tube with a paying adult. Ages 11–15 get the 11–15 Oyster discount.
Booking ahead: Warner Bros. Studio Tour needs months of advance booking. Immersive Gamebox, the Churchill War Rooms, and the Postal Museum Mail Rail all benefit from advance booking too. Everything else is flexible.
Food budget reality: London is an expensive food city. Budget USD 60–100 per day for a family of four eating one restaurant meal and snacking otherwise. Pret a Manger, Itsu, and similar chains are significantly cheaper than sit-down restaurants for lunch.
Free museums strategy: The Natural History Museum, Science Museum, and National Gallery are world-class and free. Use them as anchors on days when your paid activity is in the same area.
What to skip: Skip the London Eye for families with younger children — the queue-to-experience ratio rarely works in your favor. The views from Primrose Hill or the top of the Tate Modern's Blavatnik Building are comparable and free.
3-Day Summary Budget
| | Budget version | Full experience | |---|---|---| | Day 1 (Sightseeing bus + National Gallery + dinner) | USD 180 | USD 280 | | Day 2 (Warner Bros. + Natural History Museum + dinner) | USD 230 | USD 280 | | Day 3 (StreetHunt + Farm + Gamebox + dinner) | USD 160 | USD 250 | | Total activities | ~USD 570 | ~USD 810 |
Food and transport are on top of these figures. A realistic 3-day London family budget including food and travel runs USD 1,200–2,000 for a family of four, depending on hotel and how much you eat at restaurants vs. self-catering.
