I've had no problem with skipping the neutral week on the pill. For my wedding/mtb wedding vacation I did it a couple of months beforehand, thus moving the overall schedule up a week. I was on the regular pill, not the mini version, which does not work for me at all.
Of course, the talking to the doctor thing is important and this prattle is moot if not on the pill. You know, now they've got birth control that gives you a quarterly cycle. That I've never tried and know darned little about.

Have a great time!
