"No Vacations" - is that a Freudian slip? :)
What is the average number of weeks an employee takes? I think that would be a good metric to mention generally.
The second part you may have missed is "You can take as much or as little time off as you like." We feel if you are happy our customers will be happy! Why have fixed vacation periods, its more important to take breaks when you need them to prevent burnout.
