All I can say from my experience watching my package crossing the country by UPS is that they seem to always find a way for the box to sit for a whole weekend in some lot/warehouse/sorting center. You can see its arrival scan and its departure scan 2-3 days later. Drives me nuts. I try to spec Fedex or USPS when shipping. When I worked for the Post Office in a bulk mail center, we had a rule that any package that came thru the gate, left a maximum of 20 hours later and we worked weekends. It comes in Saturday at midnight, it better be gone by Sunday noon.
