I'd just shit my pants on liftoff.

That's really on spot but maybe it won't be your case. Many people don't like accelerations. Braking and turning a car a little harder than usual is much less that 1 g but some people don't feel comfortable with it, even when there is no danger. Remember motion sickness and the puke bags on planes. Lifting off with a rocket is always going to be higher g than with a plane. Furthermore it's probably going to require some amount of fitness. Too young or too old: fly on a plane. In the middle: it depends.

That's where the vacuum of space will clean up.

I think personally I'd keep my seat belt on regardless even if there were restrooms

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.
