Question:
Is it permitted to take a vacation after the shloshim for my mother?
Answer:
Hamakom yinachem eschem btoch shar aveilei t'Zion v'Y'erushalayim,
The answer to your question depends on why you are taking the vacation. In general, if it is needed for emotional or health reasons then it is permitted. O eodes have to be cautious though, not to engage in joyous social activity when vacationing.
Best wishes
