For those who travel for work I would like to pose a question: when does your vacation start and end? What I mean is if you take a Friday off of work for example when do you expect or think is reasonable to return home on Thursday evening? And the flip side if you are returning from a week off do you think travel on the Sunday after your week off is reasonable or would you travel on Monday?

The way I look at it my vacation starts at 6pm on Thursday (in the above example) and ends on Sunday night - meaning I need to be "on vacation" at those times which may result in me leaving the work location early/arrive late to accommodate that. Is that a rational/reasonable way to look at it?
