I think in this day and age, whatever you want to choose is fine. I honestly think it depends on the way you were brought up, and all that jazz. My mom has a hyphenated last name, i.e. maiden name-husband's last name. My stepmom took my dad's last name, my sis kept her last name. Everybody's cool with it. I don't hink it's a very big deal at all, to be honest.
