When I was still on the pill, I used to skip my period if I was going out of town on vacation and I didn't have any problems with spotting or breakthrough bleeding. But then, I'd been on the pill for at least 12 years before trying it the first time.
Anyway, some women do get spotting or bleeding when they try to skip a period, but some don't. And as long as you don't do it ALL the time, then you should be fine. Instead of taking your placebo pills, you would just start a new pack right away. And then at the end of that pack, take the placebos (or throw them away, whatever), and just take your new pack after you've had your withdrawal bleed.
