今 = now, at this moment
冬休み = winter break but more formal to say winter vacation or holiday
期間中 = this is tricky because it means "during" or "the duration of"
ですか = polite phrase being posed as a question in Japanese with no English equivalent.
Are you in the middle of your winter vacation? = there is no 今 or now because the sentence is in present tense. Middle is probably one of the closest alternatives I can think of for 期間中.
Are you on your winter vacation now? = On your winter vacation is another alternative to 期間中 I can think of since "on" is a preposition used in this to indicate a state of something.
Is it winter vacation for you now? = No 期間中 equivalent so it's more straight forward.
今 = now, at this moment
冬休み = winter break。
よりフォーマルには winter vacation/holiday
期間中 = during または the duration of
ですか = 日本語における質問の丁寧なフレーズに付けられる、英語に同等のものはない。
Are you in the middle of your winter vacation?
= 文が現在形なので、now はありません。
Middle が、おそらく最も「期間中」の代替として近いと思います。
Are you on your winter vacation now?
= On your winter vacation は、前置詞のonがここで使われることで何かの状態を示しため、「期間中」の別の代替表現となると思います。
Is it winter vacation for you now?
= 「期間中」と同等のものはなく、より単刀直入です。

Are you on your winter break?
Is this your winter holiday?
How lucky for you. Is this your winter vacation?
どれも同じ意味を持ちます。

I am assuming that it is winter in your country and the customer is staying at the hotel you are working at and you want to ask if they are coming for leisure or business. Leisure means fun,holiday or vacation. You can use structure your sentences using the sentences above.
Excuse me I am curious...are you here on a winter break?... or do you live here?
A winter break equates to a holiday, or change of pace...It could be for just a few days... or even go on for weeks;-D I might pose the question like this:
"Excuse me I am curious. Are you here on a winter break or do you live here?"
A winter breakとは、休暇と同じです。数日間だけだったり、何週間もとったりします。
"Excuse me I am curious...are you here on a winter break?... or do you live here?"
すみません、ちょっと気になったのですが、冬休みでここにいるのですか、それともここに住んでいるのですか？
▪Are you here for the winter vacation?
▪Are you taking a winter break?
Example
You: Welcome to Japan. Are you here for business or pleasure?
Customer: Pleasure.
You: Nice, are you here for the winter vacation?
Customer: Yes I am, thank you.
▪Are you here for the winter vacation?
（あなたは冬の休暇中はここにいますか？）
▪Are you taking a winter break?
（あなたは冬休み中ですか？）
例
あなた：Welcome to Japan. Are you here for business or pleasure?
（日本へようこそ。ビジネスや休暇でここにいらっしゃるのですか？）
お客様：Pleasure.
（娯楽です）
あなた：Nice, are you here for the winter vacation?
（いいですね、冬の休暇でここにいるんですね？）
お客様：Yes I am, thank you.
（はい、そうなんです、ありがとうございます。）
We can either use the words, "vacation," or, "holiday," interchangeably and still keep the same meaning of asking the person if they are on vacation. We can also change the subject of the sentence to, "winter holiday," with the possessive pronoun, "your," to still keep the same meaning.
