How would I say "Sorry to disturb you" in Chinese? 不好意思打扰你一下
is "不好意思打扰你” or “对不起,打扰你” correct? yes, correct, but you might want to add the 一下 part in order to "soften" your tone.
"不好意思打扰你” 还是 “对不起,打扰你” 对吗?both are ok
Also, How would I add a time, for example, "sorry to bother you during spring vacation"?
不好意思春节还打扰你 is the how you should start your conversation.
Hope it helps
