We did stay in the 50's building facing the pool. It was a little noisy at night. I would request the 50's building facing the lake 4th floor possibly. I did hear that this is a quite spot and you can see the fireworks from epcot.
No, there are no coffee pots in the room. Sorry, you will have to go to the food court for your morning fix.
Yes, there is a safe in the room along with a hairdryer, iron and ironing board.
We did not rent a car so I could not help you with directions.
As for the refrigerators, I did hear some people post that they paid extra form them. Maybe they give you them free for medical reasons. I am not to sure about this.
We brought a collapsable cooler and filled it with ice daily. It worked out fine.
