Cultural Tip
In many Spanish‑speaking countries it’s customary to ask about the duration of a trip before confirming participation, especially in family or group travel. Using the periphrastic future (va a + infinitive) sounds natural and slightly informal; for a more formal tone you could use the simple future: “¿Cuánto durará este viaje?”. Also, remember that the accent on “¿Cuánto?” distinguishes it from the adjective “cuanto” (as much as).
