Planning out vacation days....PTO??

So...along with my first job also comes my first allocation of PTO days.  My company has taken the PTO road: each employee has a certain number of days to use for whatever they want - sick days, vacation time, etc.  I have been asked to semi plan out my PTO time...this is hard - I don't have Spring Break built into my schedule, nor do I have a month long Winter Break planned for me...  So do I plan my own Spring Break??  I am not sure...who do I go on "vacation" with?  My sisters in college??  Ummm....  Do I plan my own Winter Break?  This is a wonderful thing to ponder, I am not fretting over it, rather I am unsure of how to attack this task of planning out my vacation.
