Is there availability for more nights?
'Disponibilità' — stress the final syllable: 'dis-po-ni-bi-li-TÀ'. 'Altre' — 'AL-tre'.
Use to check availability before committing to an extension. More cautious than directly requesting the extension.
'C'è disponibilità' = 'is there availability'. 'Altre notti' = 'other/more nights'. This question is preliminary — it checks the situation before making a formal request. 'Disponibilità' is the key word in Italian hotel availability contexts.
Siete completi per le prossime notti?
Are you fully booked for the coming nights?
'Siete completi' = you are full — the opposite of what you hope to hear
Avete ancora la mia camera libera?
Do you still have my room free?
Asks specifically about keeping the same room
C'è qualche camera disponibile per il weekend?
Is there any room available for the weekend?
Asks for any room, not necessarily the same one
Italian hotel availability fluctuates significantly by season. Summer coastal resorts and Venice during Carnevale fill weeks in advance. City hotels in Rome, Florence, and Milan are busiest during trade fairs (fiere) — check the local fair calendar before assuming availability.
