Also don't take any females with you as they are definitely not welcome in the country :-O
Females are very welcome, and they still make up around 50% of the Saudi population
They are just not welcome on the same terms - especially re: driving, employment and so on and I doubt you could even check in to an aiport hotel without names matching on passport.
As a transit passenger, you shouldn't have so many problems - although you are still a guest, you are only there for a few hours and moving on.
