I've finished this game, but I didn't get the optimal ending. Being the perfectionist that I am, I've decided to re-play and figure out the things that I missed. Starting with the first section of the game (at the hotel), does anyone know...

• Can you do anything with the safe in the manager's office?
• How do you get tools from the toolbox (the one that's outside, not the one that's inside by the stairs)?
• When you stand next to the main character's bed the gears symbol appears. However, all the character does is talk about how tired she is. Can I do anything else here?
• How do you get to the area behind the hotel (where the dock is, not where the patio is)? I'm convinced that this must be possible because I saw a screenshot with the main character in that area during the day (not during nighttime, which happens later in the game). Here's a link to the image I'm talking about.

Thanks for any help you can give me!
