The shoulder seasons are objectively better for under 2s. Daytime temperatures sit between 22°C and 28°C, the sea is swimmable from late May, and kids clubs are open but not full. Avoid the four weeks from mid July to mid August unless you're prepared for 35°C+ heat that makes outdoor naps impossible.
Country specific guidance: Greece and Cyprus run April to October with shoulder seasons in May and September-October. Spain's Costa del Sol stays warm into late October. Portugal's Algarve has a slightly later start (mid May) and earlier end (early October) for reliable swimming. Sardinia and Puglia peak in June and September. Austria's Familotel resorts run year round, with summer (Alpine hikes, lake swimming) and winter (snow, indoor pools) both excellent for babies.
Easter week is a wildcard. Some resorts open Easter weekend, others wait until May. Always check opening dates for the specific kids club you're relying on, not just the hotel.
More from the FAQ
What is the youngest age for a hotel kids club in Europe?
Several luxury European resorts accept babies from 4 to 6 months in supervised childcare; a handful in Austria take infants from as young as 7 days.
Are hotel baby clubs safe?
The best are very safe; the worst are essentially unsupervised playrooms. Look for published staff ratios, dedicated baby carers, and recognised qualifications.
Are hotel kids clubs free?
It depends. All inclusive resorts usually include kids club; many luxury non inclusives charge €20 to €50 per session for under 2s.
How do I choose a baby friendly hotel?
Filter by kids club minimum age first, then check beach reality, buggy access, and whether childcare quality is genuinely verified rather than marketed.
