Most of the Paradise Pier rooms have 2 queen beds and a daybed/sofa/pull-out bed (which is kind of a convoluted contraption to pull out, but it's workable!). I think the Paradise Pier actually has many more rooms with 2 queen beds than rooms with 1 king bed.
Most of the rooms are meant to accommodate up to 5 people. You can fit 2 people per bed and then pull out the sofa bed for the 5th person. In your case, since you will have 4 people, a couple of them can sleep solo.
As the previous posters mentioned, the refrigerator is a mini-fridge (inside the armoire) with a teeny tiny freezer compartment. I always bring a bunch of water bottles with me and stash them in the Paradise Pier fridge when I stay there and they are really cold after a few hours! For such a small fridge, it gets things very cold!
There are also really cute bath products with Mickey ears on the caps in the bathroom, and there are fun little nautical/beach/sun-themed accents around the room, like a seashell soap dish, a lifeguard Mickey lamp, etc.
