a slipjoint is the way to go man. case peanut would be a good choice. just check it and if someone does take it just snag another on the other side. Mailing something on vacation seems like more hassle than its worth to me.
that said, use the USPS. they need and deserve your business. not to say that ups is up to anything but i always will go a little bit out of my way to support postal wokers.
