I just returned from about a 7 year break, with 120 jumps before I quit....various TDYs to Afghanistan as well.. Anyway, as others have said, its like riding a bike. I sat in on some of a first jump course, for the malfunctions, cut away practice, etc.
Then for the recurrency jump, we did a 2-way that felt almost like I hadn't ever quit skydiving.
dont forget your reflective belt...
