'Best ocean view' depends. From in the room, from the balcony, over the top of the bar building. All very subjective. Building 2 has rooms that look directly toward the ocean, but it is set back.
Personally, I would request building 1, 1st, 2nd, or third floor. (I think the upper floors are the 'Plus' level rooms), room #6,7, or 8 - those are the closest to the ocean. Rooms 3,4,5 will be too much in the tree branches to give a great view.
I stayed in 1105 once and loved it. It was a reasonable view of the ocean from the living area and of course the balcony area. That's building 1, floor 1, and room 5. (1st floor is actually the second level) The first floor balcony juts out about 3 feet extra from the other levels which really adds to the view. Bonus there was the ability to only take one flight of stair up/down and avoid the elevators when things are busy. 2nd and third floor would have been ok also, but would be getting up into the branches of the big oak tree.
