How does boarding typically go? What security measures do they use? Are there certain things that are prohibited, etc??
check out the before you board section on RC's website. of course guns, explosives, etc.. are prohibited. there is no liquid restriction like on planes.
i can recommend though-if you only have a bit of luggage that you can carry to just bring it to your stateroom yourself-that way you dont have to wait for it-it can take hours.
