I just looked at the Host floor plans on the website. It seems like you have to open at least two slides on all of them to use the bathroom. Maybe I'm wrong. But, they are sure are nice when they are all open.
My older Host has two opposing slides, but the wet bath is at the back just inside the door. I and DW can squeeze by the slide to get to the restroom or fridge if needed. It's more common for us to open it all of the way when we stop by the side of the road, but we also can barely open if wanted. Ours is also usable with the slides in. We've sampled like that before in extremely cold weather.
There are advantages and disadvantages of each floor plan. You just have to decide what you want to tradeoff.
