tonyh: You'll only have to buy the six month membership once. After that your renewal will be in May or June and then you can go back to buying it yearly. This would seem to maximize how many vacation days you could receive by spreading them out over the whole year in six month allotments. When January 1st rolls around you'll get 30 days. Then you renew for a year in June and get reset to 30 days for the remainder of the year knowing the reset for the following January will get you back to 30 days again.
