"I'm quite excited and the majority of the guys understand exactly what I want, what my standards are and what I am asking them to do," Saints boss Hughes told the club's official website.
"We are looking forward to it, there's some good quality games within the two weeks.
"The point is to get the majority of the guys back and we've got a few new faces as well, so that's always good to be together as a group for a certain length of time. It helps new guys to integrate.
"So we've got the benefit of a good three, four months work, going into the new season."
