The safes are bigger than the ones at wdw. They are more like those you will find in most city hotels, with a programmable combination locks. I am pretty sure you can fit a 35mm camera, but didn't try, but we did put a laptop, two tablets and wallets / papers in the safe when we went to the beach with no problem.
We were staying in a regular room, not a dvc apt so I am not sure about the coffee pots there, but the coffee maker was small, only two cups, I think. I would use it to have a cup on the balcony while DW/DD got ready and then I used my refillable mug for coffee.
