Hi Jenn !

I think that, one way or another, parents will end up paying for your holidays. If you do not charge them directly, your monthly rate will go up so that you can afford to go on holidays without worrying about not getting any income during those days. If you do charge for your holidays, your rate will stay low, but parents will pay during your holidays.

In the end, it really depends about what parents are confortable with. Maybe advertising a lower rate can bring more customers though; but will they find that you're "exagerating" for asking them to pay for your vacations ?
