If you can't sit together then you may have to sit 'seperately' or in two groups of 2
So you could tell the clerk 'We can sit seperately' but you may want to say 'we don't mind sitting seperately' this suggests you are happy to all sit on different tables
To be 'split up' means the same as being seperated
一緒に座れないのなら、二人ずつ、'separately'（別々に）座らないといけないかもしれません。
店員さんに、'We can sit seperately'（別々に座ってもいいです）と伝えることができます。ですが、'We don't mind sitting seperately'（別々に座っても構いません）と言った方がいいかもしれません。これは、別々のテーブルに座っても全く問題ないというニュアンスです。
'to be split up'は'to be separated'（分かれる）と同じ意味です。
At a restaurant. It's crowded. You are a group of four. You want to tell the staff that you can sit separately in two groups of two. In this scenario, either of the above statements should be adequate.
You can divide us in groups of two if you need to.
You can split us up in groups of two if you need to.
The two sentences you see provided above are great ways to express to your listener that you do not mind separating the group you are in. In the second sentence you will see the term split something up. This means to separate or divide something. This is a term that is common in our everyday conversation and it would make a great addition to your vocabulary.
"Is there room to sit at separate tables?" is a polite way of asking the person seating you whether it is ok for your group to sit separately, and if there is enough space for this.
"Are there two tables for two instead?" is a bit more specific, and helps the person seating you to know exactly what it is that you are looking for, and to see if it is available.
I hope this helped! :)
"Is there room to sit at separate tables?"
（別々に座ることはできますか？）
ここでは、スタッフに別々に座ってもいいか、それだけのスペースがあるかどうか丁寧に確認しています。
"Are there two tables for two instead?"
（代わりに2人用のテーブル2つはありますか？）
これはもう少し具体的です。何を求めているのかを明確に伝えて、それが可能かどうかスタッフに確認しています。
助けになれば！：)
