If it's truely a scooter, yes they do charge them outside the cabin unless someone is permanently confined to the chair like some of the power chairs. Then they charge them inside the cabin so they're available if needed through the night. Some modern ships have charging stations in a type of closet on the decks so they're out of the traffic. You just call an ext they provide and they retrieve it for you. My main concern with the suite she's chosen is if a chair will fit through the doorway of the cabin and things like turning radius in the bathroom with grab bars, shower seats and things that may be needed.
