I can see why hotels, such as Marriott, use the compact models, but they are seriously lacking. The soap dispenser door doesn't open, it hits the rack, preventing the soap from dispensing.  Also there is no air dry feature, so it takes forever for them to dry.  I believe this is the reason the housekeeping staff doesn't use the unit when they come in to clean, they do them by hand.  If I were head of equipment procurement for the hotel chain, I'd be contacting you about replacing ALL the units with something better because this model has serious design flaws.
