You kidding? There's no way I'm staying in my seat during zero gravity. I might pay more to do a couple of extra orbits and play around before coming down.

I reckon everyone would be out of their seats as soon as boost is done. Getting everyone back into their seats in time for re-entry might be the issue ("take the nearest available").

Earth to earth flights would be sub-orbital though, so no opportunity for extra orbits.

I'm gonna miss the ding of the seatbelt sign.
