Jerry Pournelle once suggested that while there is no place to "go" in space, that "doing things" in space was always entertaining in its own right. And by "doing things" he strongly hinted that he felt that "doing it" would be the strongest driver.
I expect he is correct, and don't doubt for a minute that if the Bigelow Space guys figure out how to deploy a hotel in space, an entrepreneur will deploy a bordello.
Nausea and not having any idea how to move around effectively in space probably mean a space love hotel wouldn't be a good idea, despite Pournelle's hopes.
Actually that is one of the novelties. If you've got a lot of experience you know all the 'moves' but you lose some of the 'fun' of figuring things out.
