Im claustrophobic so when I first saw my inside room...I freaked out a bit. Then I found out its not too bad if you stay out until 4am and solely use the room to sleep...lol.
Also, talking about the dark...on the epic (and probably on other boats) you keep your key card in the light switch to turn the lights on. Im ashamed to admit it took me too long to figure that out and almost cost me a broken toe by running into the closet...lol. well, makes for a funny story anyway.
