How many people can be in the taxi?
'Persone' — 'per-SO-ne'. Three syllables; stress on the second.
Ask when travelling in a group to confirm whether everyone can fit in one vehicle or whether a second taxi or a larger vehicle is needed.
'Quante persone' means 'how many people'. 'Possiamo essere' uses the modal 'possiamo' (we can) with 'essere' (to be). Standard Italian taxis carry a maximum of 4 passengers; minivan taxis carry up to 7.
Siamo in cinque. Entriamo?
There are five of us. Can we all fit?
States the number and asks if it works.
C'è un taxi grande per sei persone?
Is there a large taxi for six people?
Requests a minivan or maxi-taxi.
Dobbiamo prendere due taxi?
Do we need to take two taxis?
Accepts the need to split the group.
Italian standard taxis (usually Fiat Doblo, Dacia Duster, or similar) carry 4 passengers. For groups of 5–7, 'maxi-taxi' (minivan taxis) must be booked — they cost slightly more but are widely available in major cities.
