What time does it usually finish?
'Finisce' = fi-NI-sce. 'Solito' = SO-li-to, stress on first syllable.
Ask this when you are planning your evening or need to know logistics. It also opens a conversation about the typical pattern of this host's parties. Italian parties often run much later than expected, so the answer may surprise you.
'Di solito' (usually) is a key Italian adverbial phrase for habits and routines. 'A che ora' (at what time) is the standard time question. 'Finisce' uses the third-person singular of 'finire' — an -ire verb that conjugates irregularly by inserting '-isc-'.
Si va avanti fino a tardi?
Does it go on until late?
Less specific — asking about general lateness
Le sue feste di solito vanno per le lunghe.
His parties usually go on for a long time.
Statement about the host's typical pattern
Ho l'ultimo treno all'una. Ce la faccio?
I have the last train at one. Will I make it?
Practical timing concern — very relatable
Italian parties are famously long — a typical dinner party or social gathering may start at 8 or 9 pm and end at 2 or 3 am. This is especially true in southern Italy and in the summer months. Leaving early ('andarsene presto') before midnight is sometimes considered slightly impolite unless you have a genuine reason.
