Quick planning tips

• Best time: for south/west coast and cultural triangle travel, November–April is usually best; the east coast is best May–October (monsoon timing matters). (thetimes.co.uk)
• Mix & match: a common family route is (a) arrive Colombo/Negombo, (b) cultural triangle (Sigiriya/Habarana), (c) safari (Yala) or straight to the south coast for beaches — drives are long, so plan 2+ nights per stop. (Hotel sites above list family-room options and activities.) (jetwinghotels.com)
• Book extras: ask about interconnecting rooms, babysitting, kids’ menus, and whether kids’ club hours match your sightseeing plans.

If you tell me the ages of your children, how many nights and which part(s) of Sri Lanka you want to visit (beach, cultural sites, safari, or a mix), I can suggest a 7–10 day family itinerary and ideal hotels for each night.
