Plenty of resorts and hotels cater to families — Disneyland, for example. Others, like this fancy-looking location, focus on couples and singles. Fair enough. However, what happens when guests aren't romantically involved with the person or people in their hotel room? Shower times need to be on a rota, or things could get pretty awkward. Even some couples would find this centerpiece shower cube a little bit exposed, surely.
The other logistical consideration is the windows. Depending on what floor this is on, guests presumably need to remember to roll down the blinds before hopping in the shower, which kind of kills the vibe.
