Learn Italian: Signora, quando arriva in albergo? - Madam, when do you arrive at the hotel?

In English we say 'when do you arrive', but Italian doesn't use helper verbs like 'do' or 'does' for questions. You just put the question word quando (when) right before the verb arriva (arrive).

The translation says 'do you arrive', but isn't arriva the form for 'he' or 'she'?

Yes, it is! But here it is being used as the formal 'you'. Because the speaker is talking politely to a Signora (Madam), they use the formal Lei form. This polite form uses the exact same verb endings as 'he' and 'she'.

Why doesn't the sentence include the word Lei (you) if it is formal?

In Italian, you usually leave out subject pronouns because the verb makes it clear. Even in formal speech, you can leave out Lei unless you really need to emphasize who you are talking to.

Why do we say in albergo instead of using a word for 'to' or adding 'the'?

For certain places, Italian uses the preposition in with no article (the word for 'the'). You just have to memorize these common phrases, like in albergo (to/at the hotel), in banca (to/at the bank), and in farmacia (to/at the pharmacy).
