이용권 means a ticket, pass, or voucher that allows you to use something.

In different contexts, it could mean:

• an admission ticket
• a day pass
• a membership pass
• a usage voucher

So in this sentence, 이용권 refers to the kind of pass/ticket someone has, and the operating hours vary based on that.

-에 따라 means according to, depending on, or based on.

So:

• 이용권에 따라 = depending on the pass/ticket
• 날씨에 따라 = depending on the weather
• 상황에 따라 = depending on the situation

This pattern is very common when one thing changes based on another.

Because 따라 in this grammar pattern normally comes with 에.

The fixed pattern is:

• Noun + 에 따라

Examples:

• 사람에 따라 생각이 달라요.
• 계절에 따라 가격이 달라요.

Without 에, it would not sound correct for this meaning.

Also, this 따라 is not the verb meaning to follow in a literal sense. In this grammar pattern, it means according to / depending on.

운영 시간 is a noun phrase made of:

• 운영 = operation, running, management
• 시간 = time, hours

Together, it means operating hours or hours of operation.

Korean often writes these kinds of noun combinations as separate words, even though in English we may think of them as one unit. So 운영 시간 being two words is normal.

Because 운영 시간 is the thing that is different.

In this sentence:

• 이용권에 따라 = depending on the ticket/pass
• 운영 시간이 = the operating hours
• 달라요 = are different / vary

So the sentence is structured like:

The operating hours vary depending on the pass.

The subject marker 이/가 is used because 운영 시간 is the subject of 달라요.

Because 달라요 is the correct polite present form of 다르다 (to be different).

This happens because 다르다 is a 르 irregular verb.

Conjugation:

• dictionary form: 다르다
• polite present: 달라요

Similar pattern:

• 모르다 → 몰라요
• 빠르다 → 빨라요

So 달라요 is the natural conjugated form, not a separate word you just have to memorize without explanation.

Here it comes from 다르다.

• 다르다 = to be different
• 달라지다 = to become different / to change

So:

• 운영 시간이 달라요 = the operating hours are different / vary
• 운영 시간이 달라져요 = the operating hours become different / change

In this sentence, the idea is not really they are changing right now, but rather they differ depending on the type of pass, so 달라요 is the better choice.

It can often be understood as are different or vary, depending on context.

In English, we would naturally say:

• The operating hours vary depending on the pass.
• The operating hours are different depending on the pass.

Korean 달라요 often covers both of those ideas.

So even though the literal feeling is are different, the most natural English translation is often vary.

Yes. That would be perfectly natural.

The difference is politeness/style:

• 달라요 = polite everyday style (해요체)
• 다릅니다 = more formal polite style (합니다체)

So:

• 이용권에 따라 운영 시간이 달라요.
  sounds friendly-polite, common in conversation or casual notices
• 이용권에 따라 운영 시간이 다릅니다.
  sounds more formal, common in official announcements, websites, signage

Both are correct.

Yes, Korean word order is flexible as long as the grammar markers are clear.

For example, these are all natural:

• 이용권에 따라 운영 시간이 달라요.
• 운영 시간이 이용권에 따라 달라요.

Both mean essentially the same thing.

The first version puts early focus on depending on the pass.
The second version starts with the operating hours.

Korean often moves phrases around for emphasis or flow.

It could be added, but it is not necessary.

For example:

• 운영 시간은 이용권에 따라 달라요.

This would mean something like: As for the operating hours, they vary depending on the pass.

Without 은/는, the sentence is a bit more neutral and straightforward:

• 운영 시간이 달라요 = the operating hours are different

With 은/는, it feels more like you are setting operating hours up as the topic.

Both are natural, but the original sentence is very standard.

They are similar, but not always exactly the same.

• 운영 시간 = operating hours
• 영업 시간 = business hours / store hours

영업 시간 is very common for shops, restaurants, and businesses open to customers.

운영 시간 is a little broader and can be used for:

• facilities
• services
• programs
• transportation
• institutions

So in a sentence about passes or tickets, 운영 시간 sounds very natural because it refers to the hours during which the service or facility operates.

It is very natural. It sounds like something you might see:

• on a website
• on a sign
• in a notice
• in customer service information

It has a clear, practical, informational tone. Korean often uses this kind of structure in public-facing explanations:

• 상품에 따라 가격이 달라요.
• 나이에 따라 요금이 달라요.
• 계절에 따라 운영 시간이 달라요.

So this sentence is a good model for a very common pattern.
