「○泊○日」という言い方を英語にする時は、「○ nights and ○ days」というのがまず一般的でほぼ唯一の表現方法だと思います。
従って、「２泊３日で[旅行](https://eikaiwa.dmm.com/uknow/questions/44579/)に行ってきました」というのは、上記英訳例のように；
”I went on a trip for two nights and three days"
と言えばほぼ全体的に直訳の文、表現となりますね。
参考になれば幸いです♪
日本語ではほぼ必ず「◯泊✕日」と言いますが、
英語圏で[旅行](https://eikaiwa.dmm.com/uknow/questions/44579/)パンフレットを見ても「◯ nights」としか書かれていませんし、
口頭で確認する時も「3日」の部分は言いません。
通常は2泊なら3日になるという了解があるためです。
したがって、実際には
I went on a trip for two nights.
だけで「3日」には触れなくてだいじょうぶです。
two-night trip のように言えば「2泊3日の旅行」と表現することもできますよ。
All of the above phrases are good to say.
If you went at a weekend, Saturday and Sunday, you can also say I went on a weekend trip.
If your weekend trip includes either the Friday or the Monday - you can say - I have had a long weekend away.
Hope this helps
Jane :)
上記のフレーズはどれも良い言い方です。

参考になれば幸いです。
You explained already to your friend all the details of your trip : the places you visited and the people you met. Also, you mentioned something about the local cuisine. Your friend asks you:
"Was the weather good?"
"Yeh, it was sunny every day!"
"And how long did it last?"
"The length of my trip was 2 nights and 3 days"
あなたは旅行の詳細を説明しました。訪問した場所や出会った人々のこと、そしてその地域の料理などについても。
友人は更に訪ねます：
"Was the weather good?"（天気は良かった？）
"Yeh, it was sunny every day!"（ええ、毎日とても良い天気だったよ）
"And how long did it last?"（何日間行ってきたの？）
"The length of my trip was 2 nights and 3 days"（２泊３日の旅行でした）
A trip is another word of vacation or holiday. When you go on a trip, you go away from your home, to a different location (state, country, etc.) for a period of time. People often go on trips for leisure, business or to visit family or friends. 2 nights and 3 days is the duration of your trip.
trip（旅行）とは、別の言葉ではvacationやholidayと言います。tripとは、ある期間、自宅から離れた場所、別の州や国などにいくことを意味します。娯楽のために旅行に行く人もいれば、仕事で、または家族や友人を訪ねに行く人もいます。2 nights and 3 daysは、旅行の期間です。
"I went away for three(3) days." This explains that you were away for three days. It is not necessary to mention the two nights as people will include this in the three days.
"I was away for two(2) nights and three(3) days." this tells the person that you were away for that period of time.
"I went on a short trip." When saying you were away for the short trip this normally refers to a time less that a week.
I went away for three days.
3日間出かけていた。
この文は、3日間出かけていたという表現です。話相手は、3日間出かけていたというと、2泊したということはわかるので特に2泊したという必要はありません。
I was away for two nights and three days.
2泊3日の旅行にでかけていた。
この文は、2泊3日間の旅行であったことを伝える表現です。
I went on a short trip.
小旅行に行っていた。
'short trip'は、ふつう1週間以下の旅行のことを指すのでこういった表現もできます。
I went on a three day trip but only slept over for two nights.
My trip was three days and two nights.
>I went on a three day trip but only slept over for two nights.
This explains that your your vacation was for three days but you only stayed over for two nights.
>My trip was three days and two nights.
This is saying that you had a trip that was three days and only two nights. This means that you returned home on the third day.
I went on a three day trip but only slept over for two nights.
*2泊3日の休暇であることを意味する表現です。

*I'm having a mini break soon for a couple of nights*- mini break- can mean anything from 1 night to 4 nights generally
