Some have gone home in 2 days but most tend to stay a bit longer, so much of it depends on travel time, home set up, how much help you may have at home, and mostly how you are feeling each day.
Many have said they end up sleeping in a recliner for awhile since getting up from laying flat is strenuous on the upper body/neck muscles.

Either way have lots of pillows or something to make into padding and support for arms and such.

I can't remember if anyone had mentioned a specific preference or reason for the surgical approach location, I think it mostly is whatever that surgeon prefers.
