Is there a possibility of a room upgrade?
up-grade — stress on the first syllable, pronounced approximately as in English.
Ask politely at check-in if there are better rooms available. Upgrades are given at the hotel's discretion and are more likely when the hotel is not fully booked.
'C'è la possibilità di' = is there the possibility of. 'Upgrade' is used in Italian hotel vocabulary as in English. Asking for upgrades is more likely to succeed when you are a loyalty programme member, on a special occasion, or simply ask very politely.
È disponibile una camera superior?
Is a superior room available?
Name the specific room category you want to upgrade to
È il nostro anniversario. C'è qualcosa di speciale disponibile?
It is our anniversary. Is there something special available?
Special occasions often unlock upgrades at Italian hotels
Sono membro del vostro programma fedeltà.
I am a member of your loyalty programme.
Loyalty membership is the strongest basis for requesting an upgrade
Italian hotel upgrades are granted on the spot at check-in, never via email in advance. The best upgrade strategy: check in late afternoon when the reception knows which rooms are available, mention a special occasion naturally, and always be extremely polite. Italian hospitality responds to graciousness.
