provided by Jeff Bezo and Richard Branson would they take off? I think it's going to be a dud because
1) prohibited cost would turn off a lot of people, and (not many people would have $200K or pay $200K to experience weightlessness). One could hire a Boeing to take him/her to some elevation, or go to science center in his area, he could experience the weightlessness
2) there's a good chance, one would throw up or would be killed (like those space shuttles were not really that safe because they were subjected to the extreme conditions and applications: high temperature, high speed, extreme environment, long flight, powerful thrust, ... would be tough on the materials and the machine endurance.
3) market for this type of services would be small I think. it's more of a clique market, only certain individuals would be attracted to.
4) fundamentally, generally humans don't have a need for flying, but we do have a need for climbing (probably, inherited from monkey)
. so I think it'd make more sense Richard Branson to provide air service to take people from Mount Everest's Base camp to the summit. 
or an airplane that could carry 1000 people from New York to Paris or LA to Shanghai because this is the area of interest of the average joes (around the world), and they could afford it
