What time does () arrive at the hotel?

What time do we arrive at the hotel?

A's have means that you have arrived at the hotel, and you should use the past participle after get.

C means past tense, which may actually happen in theory, because you may want to keep a diary or ask when we arrived at the hotel. But in general, I don't think so. If it is the past tense, I should actually say that I will know when I arrive, so don't ask.

D is followed by the verb ing, so it is also wrong.

To sum up, when we arrive at the hotel indicates the future, and we should choose B.
