You can book a room with a pullout at PBH just like you can at AKL. They do have them. They aren't in every room, just like at AKL.
PBH is comparable to Grand Floridian, Contemporary, Poly or Beach/Yacht Club at WDW. Paying $300/night is reasonable in comparison. You can only compare prices of the Universal hotels with the deluxe hotels at WDW that are within walking distance of the parks. The rooms, in my opinion, at the Universal hotels are superior to those at AKL/WL and they are adjacent to the parks. Deluxe rooms at the PBH are 490 square feet, much larger than the Poly and the AKL.
Here is a picture of the room for you. The small sofa by the window folds out.
