rchaw - if at all possible, you should try to complete your FP ahead of time. Based on what I have seen in this forum (and from personal experience), you can do FP earlier than scheduled in the notice. 2 weeks gained is 2 weeks gained. Please search this forum for FP experience at the location where you are scheduled to give FP, and see if early FP is possible. Most ASC locations are open on saturdays and you can drop in saturday afternoons.
Good luck.
