I sometimes here the following:
"I will be on vacation [holidays/leave] next week but I am planning to do some work on the paper".
"It turns out things were busier than I thought and I did not get to do much [or anything] on the paper."
Vacations are meant to be vacations. Work is for work time. You need the break. Furthermore, trying to simultaneously work and spend time with family or friends is usually stressful and frustrating for everyone involved.
Switch off. Take a break and enjoy it. Your productivity when you return will be greater.
