Let's do things separately (today/ this afternoon etc.)!
Why don't we spend time apart (today/ this afternoon etc.)?
誰かと一緒に旅行しても、時々別行動を取るとまた違った街が見えるので、旅行がより充実しますよね。
私からは２つの文を紹介します。
Let's do things separately (today/ this afternoon etc.)！「（今日は／午後は）別々にやりたいことをしよう。」
Why don't we spend time apart (today/ this afternoon etc.)?
「（今日は／午後は）別れて時間を過ごそう。」
別行動する時間を限定するためにtoday, this afternoon,tomorrow morning.. など文末につけるといいと思います。
I just need to do my solo thing for a while, sorry
Sorry, I'm not used to being with someone all day. I'll just stretch my legs for a few minutes.
Yes, this can be awkward
- especially when you go on holiday with a buddy and you are used to living alone. Suddenly, it's like being married!
They want to walk, you want to sleep;
they want to go by taxi, you want to take the bus; they want to see a monastery, you want to buy some clothes.
"Where are you going? It's dark outside."
"I just need to do my solo thing for a while, sorry. I'll be back soon."
特に一人暮らしが慣れていたのに休暇で友達と出かけていている時なんか特に居心地が悪くなる時がありますよね。
彼らは歩きたい、けど自分は眠い。
彼らはタクシーで行きたがって、自分はバスで行きたい。
彼らは修道院に行きたいけど、自分は服を買いに行きたい。などなど
"Where are you going? It's dark outside."
どこに行くの？もう暗いよ？
"I just need to do my solo thing for a while, sorry. I'll be back soon."
ちょっと一人で行動したくなったんだ。ごめん、すぐ戻るよ。
別行動とは、一人で行動するという意味があるので、以下の表現で伝えることができます。
Do you mind if I go around by myself?
（私一人で色々見てきてもいいですか？）
Do you mind if は 「～しても良いですか」という意味なので、冒頭におくと相手をあまり傷つけずに伝えることができると思います。
また、go aroundは「回ってみる」、by myselfは「自分で」という意味になります。
Why don't we do our own thing now, and just meet up later?
You could say:-
1. Let's separate now and meet up later.
今すぐ別れて、後で会いましょう。
2. Why don't we do our own thing now, and just meet up later?
どうして今は自分のことをやって、ちょうど後で会うの？
By asking a question and using the expression "why don't we' before the suggestion, is a very polite way of suggesting something to someone.
このように言うことが出来ます。
1. Let's separate now and meet up later.
今は別行動して、後で会いましょう。
2. Why don't we do our own thing now, and just meet up later?
お互い別行動して、ちょっと後で会うのはどう？
質問の文頭に "why don't we"を付けることによって、丁寧な提案になります。
