Cabin 813 is a cabin for disabled passengers. It has wider doors, ramps into the bathroom & onto the balcony.
There is no tub (bath) but has a huge 'wet room' style of shower.
Very good location on the ship as it is on the correct deck for The Collonade & deck entertainment and far enough away from those locations for noise not to be a problem.
Sliding doors on cupboards/closets can become tiresome as can the catches on cupboard doors.
Everything else A1, a very quiet cabin.
