Yes, you receive positive space home on the weekends. I wouldn't recommend heading home though on the final weekend prior to the systems exam. You should've already received an email about whom to contact to set up your travel needs. Class should be done on Fridays by 1700 and the hotel shuttle will take you to the airport from the training center. They may also take a vote in class to start on Fridays an hour early so you can have a few more flight options.
