That pretty much clears it up, thanks for all the replies. That OCV option does sound pretty awesome but I doubt we ever see that. I just think having to bid my vacation up to 15 months out is beyond ridiculous...I barely know what I'm doing next week. We can slide our vacation within a bid period which is great, as well as an option to grab a few days from a later vacation to drop a day (very limited). We also have a very limited ability to move up our vacation, but I have found that to be rather useless. The bank option sounds great except the vacation sell back.
Thanks again!
