Yeah, I have been thinking along those lines. I can sometimes book a Wednesday evening, so I did this week as well as the weekend ones, but it didn't turn out right today. What's worse, is that cos of work, I can't always book an evening, and I definitely can't afford to miss a lesson and still pay for it. My instructor is good about things, and would let me cancel up to a couple of days before, but less than that, and he would charge, which is reasonable, as its his livelihood I would be screwing up. And to be fair to him, the couple of times I have had to cancel (bad back instance) he didn't charge me anyway (even though I offered!)
For now, its lessons booked every week, find some poor b****er more unlucky than I am, and then not fly on the same days :-)
