This hotel is very popular, so you should book early.
The hotels in this area get booked up quickly so you should do it soon.
I would book your hotel early as they get booked up quick.
To get booked up means that the hotel is popular and the rooms will be fully booked very quickly. In the second sentence, saying 'you should do it soon' should only be used when in the context of the conversation of booking a hotel. In this case you don't need to specify for the person to book early because they already know that this is what you are talking about. You can also say that the hotel is popular, which explains why the person needs to book a room soon or early.
To get booked up' は、そのホテルが人気があってすぐに予約が埋まってしまうことを表します。
二つ目の文の 'You should do it soon'（すぐにそれをした方がいい）はホテルを予約するという文脈の中でのみ有効です。ここでは、既に相手に何についての話かが伝わっているので「すぐに予約をした方がいい」と明示する必要はありません。
また、「このホテルは人気がある」と言っても、早く部屋を予約しなければならない理由を説明できます（→例1）。

The hotels tend to fill up so book as early as you can.
You should book your hotel now to beat the rush.
You'll want to book your hotel as soon as possible to beat the crowd.
I used three phrases here to express this idea in a natural way. The first sentence uses "fill up". In this case, you're telling someone that the hotels run out of room and you don't want that to happen to your friend. The second and third sentences use "beat the crowd" and "beat the rush". Both of these phrases tell someone that a lot of people will be coming to the hotels. The "beat" the crowd or the rush is to get there first.
ここでは、三つのフレーズを使ってこの意味を自然に表しています。
一つ目の文は "fill up"（埋まる）を使っています。この場合は、ホテルの部屋が埋まる前に予約をした方がいいと伝えています。
二つ目と三つ目の文は "beat the crowd" "beat the rush" を使っています。これらのフレーズはホテルにたくさんの人が集まることを伝えます。
"beat the crowd/the rush" は「混雑する前に～に行く」という意味です。
