I'd like to do the exact same thing. There is a place where you can register on the UPS site and do that, but then I got worried that Apple might suspect it as some kind of scam or something or UPS might have some strict instructions with this regarding the ipads, so I decided to just let it deliver to the house.
Yea, I thought about this as well and not changing it. Odds are I will have to pick it up on saturday.
