Do you have availability for two nights?
'Disponibilità' — stress the last syllable: 'dis-po-ni-bi-li-TÀ'. The grave accent marks the stress.
Use early in the call to check if the hotel has rooms before going into details. Saves time if they are fully booked.
'Avete disponibilità' = 'do you have availability'. 'Disponibilità' is the key word in Italian hotel bookings. 'Per due notti' = 'for two nights'. This question is direct and immediately actionable.
Siete completi per il weekend?
Are you fully booked for the weekend?
'Completi' = full/sold out — a quicker way to check
Avete qualcosa di libero per sabato sera?
Do you have anything free for Saturday evening?
Informal and casual phrasing
Ci sono ancora camere disponibili per agosto?
Are there still rooms available for August?
For high season — 'ancora' implies you know it may be busy
August (agosto) is peak season across most of Italy. Many coastal and lake hotels are fully booked from mid-July to late August. Calling well in advance (2–3 months) is essential. September is often a better alternative — beautiful weather, fewer crowds, lower prices.
