KCDW,
When I was a very new PPL I went down to the airfield two weekends in a row, and on both days decided not to fly due to marginal weather. The second time a nearly-qualified student implied quite strongly that I was a wimp, saying he couldn't wait to get out by himself. Judging by the nods of agreement as he spoke, he wasn't alone. But I didn't go because I'd had my QXC cancelled in similar wx; I'd persuaded my instructor I could cope; then not been able to land in the gusty crosswind when he checked me out. It was a real eye-opener for me at the time. Does that answer your question of "how many" etc?
As I said, not something you'd choose, or spend hours doing. But four circuits, and only paying for two! And learning from experience just what a difference the wx can make. Sounds good to me.
