I leave my CP’s unlocked on both my Aeros and Astro City’s, so it’s just 1 step to lift open. The monitor surround and CP tops have enough of a snug fit that the friction keeps them down when playing. The CP top is also hinged, so you just swing it open and do your business.
Service door takes 3 steps. Unlock, open, then place to the side.
