Actually, an A380 can hold 853, so BFR could probably hold the same.

If he can get the cost down to US $10 million per trip, that's US $12K per person.

For 30 minute trips you barely even need toilets.

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.

Free adult diapers for all passengers!

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.
