“度假恋”用英语怎么说？

Vacationship refers to a long-distance relationship in which the couple only gets together for idyllic vacation-like excursions, therefore avoiding the "real-life" issues of dating.

“度假恋”指的是一种异地恋，恋人们只有在结伴出游去享受美好假期的时候才在一起，这样就能避免约会当中遇到的“现实生活”问题。

Example:

She met this guy online last summer, but he lives in Austin and doesn't want to move, so they've struck up this very intense vacationship.

她去年夏天在网上认识了这个男人，不过他住在奥斯丁市，也不愿搬到这里来，于是他们就开启了这段热烈的度假恋情。
