“This is an individual issue and a Rov should be asked….”
First, ask YOURSELF if YOU are comfortable. If not and you are in EY, perhaps consider spending a portion of your vacation volunteering in some venue whose regular workers have been called up for reserve duty. In the U.S., take a portion of what you had budgeted for a vacation and donate it to mosdos that are supporting those from the North who have been forced to leave their homes for over 6 months with no end in sight. While your LRP can be a helpful sounding board, its less a matter of halacha and more an issue of your personal ethics, hashkafah and comfort levels.
