Interior rooms have no windows, so they do not let the dark out (light in)!
Oceanview rooms do not have as much exterior light leaking in (as compared to verandah) ... but remember, at night, there is not a whole lot of sunlight outside. That being said, consider turning on a bathroom light ... close the door. It provide enough light (escaping under the door) ... allowing you to walk through the stateroom at night, without stubbing your piggy-toes!
Clock too bright? Turn it away from you (towards drapes or wall). Still too bright? Close your eyes!
